thanks,

Maik

What was the version and date of the code that you were upgrading from? That graph does say it all. Or as Napoleon Dynamite would say, "Sweet!"

Oh - I've got more of this. It is the munin package of debian. So If you are interested in RAM-usage...

I spend a long time to optimize the MySQL-settings to get this cache hitrate.

Well since you are offering, what is your best advice for optimizing the MySQL settings?

It heavily depends on your installation and your users. A good point to start is the following link (tuning_primer.sh):

Another hint is to turn any engine og MySQL off, you won't need, especially InnoDB to save memory.

We use lighttpd instead of apache - this saves much memory - but no one seems to have tested this on high load environments. I've got 30% more performance since using lighttpd/fastCGI.

Hi Maik,

I am wondering what your max concurrent users are when using lighttpd/fastcgi. Perhaps a good option for us.
Whan you speak of performance what do you mean exactly, faster response time on pages, or less load on the server?
