Actually the issue here is Moin's inability to cache properly.  We've 
actually added a psudo mod_headers / mod_cache type deal to get it to 
cache.  This combined with the inability to run Moin in a cluster 
without something like GFS brings forth scaling issues.  Moin is great 
for smaller deployments but I suspect we have long out-grown it.  The 
wiki did OK this last release, we did some horrible things to it (that 
caused file corruption that we later had to go back and fix) but all in 
all the wiki was more available than not according to the logs (less 
than 1% 503 IIRC)  Needless to say a lot of our problems are caused by 
design problems, not so much technical ones and thats what makes it so 
hard to stay with Moin.

Having said that, moving away isn't very feasible either.  We're in a 
tough spot for sure.
