Thanks Levente,<br>
<br>
I'll look into that. <br>
<br>

I run a Squeak image under Cog on a hosted virtual Linux server.

Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.201]
<br>
Unix built on Aug 14 2012 09:25:00 Compiler: 4.1.2 20080704 (Red

Lately I used it for some optimizations running for several days
and the Hoster complained that I create too much IO, my CPU
usage being no problem. I have no idea how I could create IO but
it occurs during my CPU usage. I do no IO I know of. Only idea
I have is accessing virtual memory. Changes file is 37MB and not
growing during the computations.
<br>
<br>
TOP tells me the image is actually using 60 MB but virtual
memory is 1GB. VM statistics reports 50 MB, 40 MB used. The
virtual server has 512 MB, 200MB free. Nothing else runs on the
machine. The server has no X running I operate Squeak through
Tight VNC tunnelled through SSH.
<br>
<br>
Is it possible that Cog frequently tries to access virtual
memory under these circumstances? The system does not slow down
compared to the same calculations on my Windows laptop where I
have sufficient memory.
<br>
<br>
Any ideas of other ways I might involuntarily create the IO
load?

IO usually means disk usage, so I don't think this has anything to
do with Cog or virtual memory. You can use iostat and iotop to see
what's using up IO bandwidth.
