I'm still not entirely sure that mod_interchange is being tripped up
by this. Something certainly is, that's for sure, so I can't rule it
out just yet. I didn't hear back about whether the same problem occurs
when using the cgi-bin executables.
Thanks for posting the packet data. I'll use that to try to recreate
the problem locally. I imagine I'll have to throttle the link and/or
fire truck-loads of simultaneous requests to get the problem to show
itself. If the problem can be recreated on demand then it can be found
and fixed. I have an old P200 that I use for performance tests. Test
time differences are amplified massively when running Interchange on a
P200 with 128MB of memory. :-)
My previous tests centred around GET requests, so POST requests might
be more useful. Mod_interchange doesn't really know the difference
between the two, but more work is done on the Interchange side when
a POST comes in - adding to the load.
If I find the culprit then I'll make the appropriate changes in
mod_interchange and/or Interchange itself. Talking of culprits, you
have the kiddie's IP address, so I'm assuming you'll be emailing a huge
slap via his ISP.
