- LZMA decompression speed was improved.
- "compress and send to email" code was improved to support more email clients.
- New command "h" to calculate hash values CRC-32, CRC-64, SHA-256 or SHA-1 for files on disk.

That improved "send to email" code was not tested enough. So please test it and write about results here.
New "h" command scans files on disk (not in archive). For example, you can use it if you want to compare two big folders.
Also there are new benchmark tests with command
7z.exe b -mm=*
You can post results of that command here at forum. MIPS ratings are normalized to AMD cpu in that test.

Yes, there is new switch -sa.
Actually I need it to send command from 7-Zip File Manager to 7-Zip GUI, when 7-Zip File Manager doesn't know archive type.
End users probably can work without that switch in most cases.

AES256CBC:2 is version of AES code that uses Intel's hardware-AES instructions. AMD will support it only in next upcoming CPU (Bulldozer)
I'll change MIPS values for AES256CBC:2 in next (9.26) version to be more close to real CPU frequency.
CRC32 and CRC64 code is written in ASM and it's optimized to be quick on AMD. So Intel is not so good for that code as AMD.

Thanks for the new version. My machine is really old so I don't think the benchmark results on my machine are useful.
New switch -sa without announcement. Why?
Yes, there is new switch -sa.

I'll fix that bug with encrypted RAR.

Round #2 (32-bit 7z.exe)
Thanks for the new version and hard work!
Hello everyone,
just for the record -> Intel N450 Atom in a PackardBell dot_SE 0.24 with 2 GB RAM:
Best regards!
