Then it tests CPU Frequency again (in multithreading mode, if multithreading mode was specified)
CPU 199 2868 5696 101 200
2868 is not correct CPU frequency here, since Hyper-Threading doesn't give full resources to each thread from two threads.
Then it tests Compression, Decompression and HASH calculation code.
MIPS - are results normalized for AMD K8 cpu.
Effec - are results normalized to CPU frequency.
For example, Effec = 130 means that CPU is 30% faster per MHz than AMD cpu.
The test AES256CBC:2 - is AES hardware test (that test is supported only if CPU supports AES instructions).
You can post results here at forum for your CPU.
Please write full name of your CPU and real CPU frequency, if you know it.
The results for two tests are interesting:
7z b -mm=* -mmt1
7z b -mm=*
Please use "Code Highlighting" for results in messages.
You can designate a code block by surrounding it with lines of tildes:
However my CPU has an IDA p-state (Intel Dynamic Acceleration) which should clock one (and only one) core at 2400 MHz (multiplier 9 instead of 8.5) if the other core is idle. I don't know if it was active during tests though, since I don't know of a reliable way to detect IDA p-states.
I'll try the above commands later (I'm on another computer right now).

However I don't know if this disables IDA, too (and I don't know software that is designed to disable IDA). Also I was never really able to test if IDA is used since
a) I don't know of a tool that is designed for this (only general tools, that show the current CPU clock).
b) IDA is never active all the time. It's only active for fractions of a second, since the limitation applies that other core has to be idle (which is very unlikely on modern systems)
If you know of better ways to test this, please tell me (I assume you have run into similar issues when benchmarking).

According to CPU-Z the CPU was running mostly with multiplier 34 (3.4 GHz) during tests.
For the test with one thread sometimes Multiplier 35 (3.5 GHz) or (seldom) 36 (3.6 GHz) was set.
(If you know how of an easy way to fix i5 CPUs with Intel Turbo Boost to a specific multiplier and need those tests, too, tell me. I could retest then.)

Now for me it's not so important to get exact results without Turbo-Boost.
I just wanted to check that CPU frequency detection works OK. In your case it showed:
3543 (-mmt1)
3380 (-mmt4)

Cpu usage is higher than 100% for single thread.
Probably GetProcessTimes() function returns incorrect results for such overclocked cpu.

Intel Core i5-3570 (Ivy Bridge) at 3600 MHz (original 3400, overclocked by 2 multiplier steps), Turbo Boost active (up to 3800 MHz); 2x8GB DDR3-1600, 9-11-11-29 (CL-RCD-RP-RAS); Windows 7 x64 SP1. I have tested both 32-bit and 64-bit versions, the latter is generally faster.
Update.Delta:4 suffers greatly from 64-bit implementation. My tests show a 18% speed drop. Why? (By the way, does it subtract 8-bit or 32-bit quantities?) On the contrary, Deflate and BZip2 decompression and SHA filters gain from 9% to 33% upon transition to 64-bit code. AES256CBC:1 shows up to 20% gain, but AES256CBC:2 has a 3% drop.
Delta code is not fully optimized still. It works with bytes (8-bit).
x64 provides some advantages over 32-bit x86 for 7-Zip code:
1) more registers: 16 vs 8. But modern CPUs are fast for stack variables, so gain in x64 is not so big.
2) There is some code that uses 64-bit integers, but it's small part of code in benchmark.
3) 32-bit code doesn't use CMOV instruction that is not implemented in old 32-bit CPUs.
Some code strongly depends on memory latency (LZMA compression). So 32-bit and 64-bit code wait data from RAM or cache for same time.
Some code is writtten in ASM: CRC and AESCBC:2. And it's optimized for both 32-bit and 64-bit.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Did you think of implementing a Delta filter for 16-bit or bigger numbers? I suggest naming them like Delta:4:1: period 4, subtract 1-byte quantities. This could give some gain for data arrays. Such a technique is already implemented in TIFF differencing. I have once implemented a Delta:8:8 filter for my scientific computations; it was better than Delta:8 even despite type difference (the original data were 8-byte reals, but I casted them as 8-byte integers for lossless filtering).
Please consider this post as a low-priority feature request.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
We were thinking about it when we selected Delta filter for xz format. Wider versions do not provide big gain, and such filter will be used not too often. So we have selected only simplest 8-bit variant.

Thanks for tests.
Some additional notes about p7zip benchmark.
1) According to your OS, copy makefile.linux,
makefile.freebsd, makefile.cygwin, ...
over makefile.machine
you can use:
makefile.linux_amd64
makefile.linux_amd64_asm
makefile.linux_any_cpu
_asm version must provide fastest CRC code for x86.
2)
Change
OPTFLAGS=-O
to
OPTFLAGS=-O2
in makefile.machine
3) SHA256 source code is not optimized for speed. So it's slow.
AES-NI is not supported in p7zip still.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Ah, definitely better speeds. I missed the part about moving the makefiles in the readme, gah! Thank you!
Reran the benchmarks and edited my post above with the new results.
Used 'makefile.linux_amd64_asm' for x86-64 and 'makefile.linux_any_cpu_gcc_4.X' for ARM.
Used OPTFLAGS=-O2 -march=native (except on the Nano, as gcc doesn't seem to know the native CPU)
AES-NI now does seem to work! I also ran a quick test using the Windows 64-bit via wine64, and got roughly the same ballpark figures, so hopefully this is more representative.
As a reference for OpenSSL speeds, scroll down to the CPU Benchmarks section here for what I get on the above CPUs using 1 thread (ignore the Nano CPU as it's using h/w accel there). I suspect OpenSSL devs have put a lot more effort into the hashing/encryption performance, since it's basically what it does. Not expecting anyone to replicate it, but I just thought it may be of interest. Ever considered linking to it maybe?

7-Zip 9.38 beta supports new benchmark that tests the speed of some code from 7-Zip (not only LZMA).
You can call it so:
At first it tries to detect CPU frequency to select the complexity of test.
Last value: 3282 is estimated CPU frequency.
Then it tests CPU Frequency again (in multithreading mode, if multithreading mode was specified)
2868 is not correct CPU frequency here, since Hyper-Threading doesn't give full resources to each thread from two threads.

If you run single thread code, then other core will be idle at 99% of time.
If you want to see exact CPU frequency, any test from 7benchmark probably can show it (it uses precision timer from CPU):

For the test with one thread sometimes Multiplier 35 (3.5 GHz) or (seldom) 36 (3.6 GHz) was set.
(If you know how of an easy way to fix i5 CPUs with Intel Turbo Boost to a specific multiplier and need those tests, too, tell me. I could retest then.)
Now for me it's not so important to get exact results without Turbo-Boost.
I just wanted to check that CPU frequency detection works OK. In your case it showed:

Probably GetProcessTimes() function returns incorrect results for such overclocked cpu.
What exact settings do you change to overclock cpu: BIOS or some program?
Probably BIOS, this system runs in a VM on top of some Linux.

Intel Core i5-3570 (Ivy Bridge) at 3600 MHz (original 3400, overclocked by 2 multiplier steps), Turbo Boost active (up to 3800 MHz); 2x8GB DDR3-1600, 9-11-11-29 (CL-RCD-RP-RAS); Windows 7 x64 SP1. I have tested both 32-bit and 64-bit versions, the latter is generally faster.
Update.
Delta:4suffers greatly from 64-bit implementation. My tests show a 18% speed drop. Why? (By the way, does it subtract 8-bit or 32-bit quantities?) On the contrary,DeflateandBZip2decompression andSHAfilters gain from 9% to 33% upon transition to 64-bit code.AES256CBC:1shows up to 20% gain, butAES256CBC:2has a 3% drop.32-bit single-threaded:

CPU Freq line (preload) uses single thread:
CPU lines in test are multi-threaded for-mmt4:
So results are correct.
Yes, I have figured that out already and edited my post. Yet thank you for the comment.
Delta code is not fully optimized still. It works with bytes (8-bit).
x64 provides some advantages over 32-bit x86 for 7-Zip code:
1) more registers: 16 vs 8. But modern CPUs are fast for stack variables, so gain in x64 is not so big.
2) There is some code that uses 64-bit integers, but it's small part of code in benchmark.
3) 32-bit code doesn't use CMOV instruction that is not implemented in old 32-bit CPUs.
Some code strongly depends on memory latency (LZMA compression). So 32-bit and 64-bit code wait data from RAM or cache for same time.
Some code is writtten in ASM: CRC and AESCBC:2. And it's optimized for both 32-bit and 64-bit.
Did you think of implementing a Delta filter for 16-bit or bigger numbers? I suggest naming them like
Delta:4:1: period 4, subtract 1-byte quantities. This could give some gain for data arrays. Such a technique is already implemented in TIFF differencing. I have once implemented aDelta:8:8filter for my scientific computations; it was better thanDelta:8even despite type difference (the original data were 8-byte reals, but I casted them as 8-byte integers for lossless filtering).Please consider this post as a low-priority feature request.
We were thinking about it when we selected Delta filter for xz format. Wider versions do not provide big gain, and such filter will be used not too often. So we have selected only simplest 8-bit variant.

Thanks for tests.
Some additional notes about p7zip benchmark.
1) According to your OS, copy makefile.linux,
makefile.freebsd, makefile.cygwin, ...
over makefile.machine
you can use:
makefile.linux_amd64
makefile.linux_amd64_asm
makefile.linux_any_cpu
_asm version must provide fastest CRC code for x86.
2)
Change
OPTFLAGS=-O
to
OPTFLAGS=-O2
in makefile.machine
3) SHA256 source code is not optimized for speed. So it's slow.
AES-NI is not supported in p7zip still.

Ah, definitely better speeds. I missed the part about moving the makefiles in the readme, gah! Thank you!
Reran the benchmarks and edited my post above with the new results.
OPTFLAGS=-O2 -march=native(except on the Nano, as gcc doesn't seem to know the native CPU)AES-NI now does seem to work! I also ran a quick test using the Windows 64-bit via wine64, and got roughly the same ballpark figures, so hopefully this is more representative.
As a reference for OpenSSL speeds, scroll down to the CPU Benchmarks section here for what I get on the above CPUs using 1 thread (ignore the Nano CPU as it's using h/w accel there). I suspect OpenSSL devs have put a lot more effort into the hashing/encryption performance, since it's basically what it does. Not expecting anyone to replicate it, but I just thought it may be of interest. Ever considered linking to it maybe?
