To switch from persitant connection to non-persistant connections you should've went to the admin control panel and changed the 'Use Persistent Connections:' option. Modifying the source files was NOT the correct approach.
Nope, this very forum does not use persistant connections and as you can see it runs pretty fast. In fact many people do not use persistant connections and I have not heard any complains about speed.
The reasons why your forum could be slow are numerous. Such as high load on the server due to other applications, old version of MySQL (some old MySQL versions has trouble resolving indexes in complex queries, which means some things are not being indexed), server is low on free memory and is using swap memory instead of RAM.
What you can do depends on what kind of access you got to the server, if you are an admin then you can improve the situation by addressing the problems I've descirbed above. Otherwise you can try to indetify the problem and contact the admin/web host and ask them to address the problem.

The other command is 'top'. You can also try to see what CPU(s) the server got, by opening /proc/cpuinfo, it is a file containing info about the server's cpu(s).

Well, some commands may have been disabled for security reasons, if you have shell access you might as well try the 'w' command there.

Yeah, that would exaplain the slowness, I imagine the server is probably on a local lan, but that still is no where as fast as UNIX domain socket or local TCP/IP connections.

. For example this server is a dual CPU box, who's load hovers around 1, meaning that 1 cpu is completely busy.
. They wrote me that there is a 'ping-difference' of 150 ms. I guess that the database connections go through the internet.
