No, works very well here.

No, colinux has its specific network problems. It has serious latency 
problems (if you don't use bridgeing just ping host and colinux to see 
the difference). Every packet gets a time penalty.

[peter g. <plu...@bi...>]

nah colinux network performance is pretty poor in general

and compiliation especilly the C way tends to hit the filesystem a lot

Re: [coLinux-users] performance

[Curtis, C. <Cra...@ec...>]

My problem had to do with network latency.  I was mounting an SMB share 
and building off of it.  When I copied it to an EXT2FS, it worked 
wonderfully.

I am now EXTREMELY happy with colinux.  This is an awesome project!

Henry

Thanks for the information.

It wasn't as bad as that, as it did work without the modules.  I 
started with FC1 and 0.6.1 and upgraded, first to 20040910 
snapshot and then to FC2, but always have had a working system.

The modules have gone in cleanly.

Thanks

John

That's why i suspect disk-io problems. If the compiler is waiting for 
the disk it will not use cpu time. A heavily fragmented file for the 
simulated hard disk could be a reason.
Do a bonnie test.
How much RAM did you give colinux?
Maybe if you have a tmpfs put all the source there and compile there.

I've just finished committing a fix for the PAE issue. It took the whole day,
and there were more extensive changes than I thought. The context switch code 
is a bit larger now (and also works differently than what you read in the 
slides and OLS paper) but expect no notable overhead like before.

Anyway, it appears to be stable on my PAE enabled XP SP2 and also on
my Linux boxes and Windows 2000 in QEMU. Users can test it by compiling
the binaries or wait until I release a snapshot this weekend.

What I like most with colinux is exactly it's speed.

I compile the colinux kernel many times and don't notice any big
difference in relation to a similar "native" linux machine I have
at my side.

I use Gentoo, and also don't notice any big differences, even when
compiling those big packages like xorg or gcc (just updated both
yesterday on both computers with no problems or very big differences).

colinux is always slower than a native linux. It's just impossible to
do better (we have to let windows run, don't we ;), but you shouldn't
notice with normal command line usage.

As a side note, I run "hdparm -tT" on the "native" system, with an old
IDE 10GB disk (reiserfs) and got:

* Cached reads: 360 MB/sec
* Buffered reads: 18 MB/sec

On a colinux "real" partition I got (with some errors ignored):

* Cached reads: 340 MB/sec
* Buffered reads: 11 MB/sec

I don't think this are bad results, even if that partition is in a more
modern IDE 7200 rpm, 40GB disk (ext2).

Maybe you should run your own tests and post the results here, so we
can help you more.

[coLinux-users] Re: performance

[Martin K. <ka...@po...>]

Hi,

there's just an issue, that not only CPU is heavily used when compiling. 
  The only performance problem with CoLinux is the networking, not the 
throuput, but latency.

--- "Curtis, Craig" <Cra...@ec...> wrote:

My short answer is, no it should not be significantly slower from the
perspective of the processor... In my experience.

Longer answer:

A few months back I did some speed comparisons between some code I wrote
running under Windows, coLinux and native Linux.  The program was a snippet of
some AI code doing a mix of int and float math using linked lists and arrays.

In any event, here is what I saw (qualatatively):
  - code compiled using intel's C compiler ran at pretty much the same speed
under windows, coLinux and Linux. (dual boot machine) Other than the initial
load of the program, there was no disk i/o.    The variation in run times was
only a couple percent at most.  
  - also, code compiled using gcc ran at about the same speed under native
Linux, coLinux and Cygwin.  These did run significantly slower than the intel
compiled binaries.   

This testing was under the 2.4 kernel.  I have since moved to the 2.6 kernel
but haven't seen significant slowdowns.

As a side note, coLinux provides a nice way to run the free Linux version of
Intel's C compiler under windows.  The speed benefit over gcc CAN be HUGE for
certian types of programs.

According to my testing, you get the full processing power of your cpu. 
I tested that with numerical simulation programms (fpu bound). It 
doesn't make a difference real linux vs colinux.
But i don't use swap at all, and know nothing about the disk speed you

Re: [coLinux-users] colinux with fedora

[Henry N. <Hen...@Ar...>]

Yes, your image had perhaps modules for older kernel. Your network would 
not work. You need an update of /lib/modules into image.
To do this, You need a running linux, but not from this image self.

Go on linux, or run Linux from other PC or boot Linux from Knoppix, 
login as root
Mount your Image fc1_2GB_root.out as loop
  # mkdir /tmp/fc1
  # mount -o loop /PathToFile/fc1_2GB_root.out /tmp/fc1
Extraxt the kernel modules into the mounted image
  # cd /tmp/fc1
  # tar xfz /PathToFile/vmlinux-modules.tar.gz
  # cd /
You will find your missing file modules.dep and directory for Kernel 
modules now, check this
  # ls -la /tmp/fc1/lib/modules/2.4.26-co-0.6.1
Unmount the loop image
  # umount /tmp/fc1

Now ist the file fc1_2GB_root.out ready to use.
Copy it to your PC for running under Windows.

[coLinux-users] performance

[Curtis, C. <Cra...@ec...>]

I just wanted to ask about the performance of colinux.  I am running 
win2000 on a 2.6GHz PC.  I set up a linux partition with debian to be 
used with colinux.  I also set the swap to a real swap partition.  When 
I go through to make a project, it is MUCH slower than a 400MHz PC.  I 
can look at my hard drive and see that the harddrive is not being 
touched almost at all during compilation, so this tells me I have enough 
memory.  Is colinux just much slower than a standalone linux PC?

take a look at http://www.colinux.org/wiki/index.php/FedoraHowTo

I think using ro root=/dev/cobd0 instead of just root=/dev/cobd0 should do
the trick.

As Steve Frank said, the "/PAE" switch is a boot.ini configuration
switch. They are for servers usage, not normal users, so not documented
in normal user documentation.

DEP is the new SP2 security feature that protects from some virus, by
using the NX feature that some new processors have. Basically, it avoids
some buffer overflow exploits, by not allowing to execute code from
normal memory. This feature is mostly only present on AMD64 processors.

You should be safe to upgrade (and I would recommend you, as many other
security fixes are included).
If you don't have an AMD64, PAE will not be enabled by default, so
current colinux versions will work ok.

Hi Steve,

Yes I have it. I renamed it to "tap" -- the properties panel "connect using:"

Currently I have the networking set up to "share" the primary internet
connection
& am following the instructions in the networking wiki. I previously tried to
use the bridging method with the same results- nada network, nada errors
too (or at least visible ones). Should I be setting up the bridge while the
colinux daemon is running?

At one point I ran through the entire "driver install" sequence as given, for
example in the Gentoo coLinux howto (networking section):
http://www.gentoo.org/doc/en/colinux-howto.xml  -- made no difference.
I also reverted winpcap to 3.0 due to the info on that page, again with
no effect.

BTW the gentoo 2.6.1 image had a bad fstab -- I've fixed that & it
mounts correctly. I can send the fixed image back if there's interest--
most people seem to use Debian with coLinux?

Thanks,
Douglas.

Doug, in Control Panels->Network Connections, do you have a device
called "TAP" ?

If so, is it Bridged against your current ethernet connection?

[Steve F. <ste...@be...>]

/PAE would be in your boot.ini on the line for the OS options. Unless
you have gigs and gigs fo memory on your machine, odds are you don't
have this set.  I have this set on some SQL Server boxes we have with
6GB of memory.

Where is the "/PAE" switch supplied?  How can I tell if it is on?  How
can I tell if my machine has DEP/NX (and what is this anyway?)?

I'm currently afraid to upgrade to SP2 (it's just sitting on my hard
disk waiting for me to click on the little icon in the tray) because I
don't understand the implications of this issue.

Thanks for any advice you can supply!

[coLinux-users] networking etc.

[Douglas F. <dpf...@lb...>]

Hi Everyone,

I have an AMD Athlon system and am trying to get
colinux cooperating with winXP with the networking.
At the moment I'm trying to get the gentoo image
working since that's what I have on my laptop.

I've tried every variation of the different suggestions
to get networking going that I can. The computer is
on a LAN & I am trying to share the winXP's internet
connection. I am following the directions in the colinux
networking section of the wiki, for shared internet
connections. The nework link in my xml file reads:
    <network index="0" type="tap" name="TAP" />

and I have changed /etc/resolv.conf to use the
nameservers here & /etc/conf.d/net to reflect the settings
given in the wiki. Networking fails to start & when I
try to restart it I get a message:

SIOCSIFADDR: No such device
eth0: unknown interface: No such device
SIOCSIFBRDADDR: No such device
eth0: unknown interface: No such device
SIOCSIFNETMASK: No such device
* Failed to bring eth0 up

Can anyone enlighten me as to what this means? I've
detached the gentoo terminal from the cmd line terminal
using -t fltk & looking at the output there I cannot see
any errors that should matter (It does complain about
a "mismatched close tag under parent"  -- even using
the default file-- but I assume that is not a critical error).
Is there another log/debug output available (another flag?),
esp. one that would give the status of all the drivers &
connections involved, before & after the gentoo system
has booted? I've tried both the beta & vers. 3.0 of the
libpcap library to no avail.

Any advice would be greatly appreciated,
Douglas.
