Cooperative Linux

What networking system are you using?
If its the bridged networking using winpcap then i have found it to be 
very slow aswell, even when conecting to the host system, whereas using 
the tap driver seems much faster.

For now, try to see if increasing coLinux's processes priorities 
has any effect.

In the next snapshot I am going to add a timestamp-based debugging 
messages that will allow us to figure out exactly where the bottleneck 
is.

I am using the WinXP network bridge,  not the winpcap.  The TAP interface
and the LAN interferace are bridged together....  It turns out that most
operations are fast except writing from colinux to the file server via smbfs.
File reading is fast.  

I am also running a samba server on colinux and access it from WinXP.  Both
reading and writing are fast in WinXP, so that is a little bit wierd :)
