[Twisted-Python] Twisted webserver performance issues (was volunteer...)

Isn't the simplest option to place a decent reverse proxy between the webserver and our clients? For example, varnish will cache and proxy simple GETs, so simple views of the front page and docs (which I imagine is a large chunk of the traffic) will be offloaded from the webserver: http://varnish.projects.linpro.no/wiki/VarnishFeatures Also, is the current installation (Db, apache + trac) all on one machine or are the DB and the webserver split already? These would be easy ways to throw more hardware at the problem. What is the current web-server configuration? Can you share traffic stats for the top 20 pages, so we get an idea of where the load is? -Tom

Hi Jean-Paul,

A server farm doesn't buy us anything, as trac can't be scaled up across multiple hosts (or even multiple CPUs on a single host).

I'm surprised to hear that.

Usually replication of servers for read requests works well with dns sharing.

Does Trac not run a database? that can go on another machine and lighten the load.

Anyway, it's your call. Keep up the good work.

I think the best option may just be to collect machine, database, and usage stats and ask the trac guys for help.
