Hi all Quick reply as im on the bus. Clay i stress tested with 100 concurrent requests, stepping up in 10s after, apache2 + cgi started swapping hard load got up to 124 before i killed the test. in 252 seconds got 11 200 responses. with nginx which has virtually zero memory footprint + the FCGI::Async based wrapper the same test topped at 1.2 load. I can show you the stats on irc if you like. So far i am handling all gets with it posts go to apache. I think the login page is one of the few posts so handing that to apache2-ssl is no bad thing We use nginx at work for big dynamic sites (millions of page impressions per day) Im happy to share what ive learnt.

I'm very interested interested in learning more about this, also. How well does it scale? My experience with FastCGI is that it can lend performance improvements, but it's often at considerable cost in terms of memory. Does the FCGI handle all the scripts or only key performance-sensitive ones, like opac-search.pl?

Hi All -
Friday evening here (west coast USA), Saturday evening in New Zealand. Chris Cormack was showing quite a few of the developers that hang out in the IRC #koha channel - his testing database of koha - fed through nginx and FastCGI.
I was absolutely amazed at the speed that pages from the opac were being delivered and watching some of the tests with speed comparisons between apache and nginx. I want to learn more. So, I would like to propose or maybe ask chris - if he would schedule a time that he could demo or even give a tutorial on nginx and FastCGI on the IRC channel (which is a good medium because those who can't make it will be able to read the logs). I am hoping that others get encouraged and want to investigate the possibilities.
So, If you're interested in this please let me/the list know and I'll bug chris to set up a time to give a tutorial.
Cheers, Brendan
Of course I'd like to encourage as many people to attend (it's surprising how much I've learned through osmosis)
