[drraw-users] Performance of the cgi-script on Apache

[Baumann, Christoph]

Hi together

 

I use drraw and I am very happy with it. But when 2 users access the
cgi-script together, the first user will get all Graph's one by one, the
seconde one has to wait.

Is this because I use templates, or is it because my webserver cannot
handle more cgi-scripts than one at a time?

Server-status gives something like this: (working on Solaris 10 with 4
cpu's and 8GB RAM. So no bottleneck on the OS)
