I'm not sure that the problem is peak load, but rather it might be 
sustained load.

The reason that swiki.net is so much more stable is mainly due to them 
focusing in on one platform (Windows NT) and making it as stable as 
possible. Also, they have a demon that will reset their server if it goes 
down. The Mac is not a great platform for running servers, so that is the 
main reason we have problems there. Unix machines are pretty stable under 
high load, so this seems to be a VM thing. John McIntosh has already done 
some great improvements to the MacVM, but it may be a bit longer until we 
get great reliability.

Peace and Luck!
