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.
