Thanks Jeff, that sounds like a smart idea. I will try later when I
have access to the server.
>Hi! What do you want to see in perf stats? Maybe you can explain your problem more in details?
Hi Alex ) I am hoping to find out which function calls are taking the
longest because to the code is taking too long to only parse a small
XML file and do a few quick database queries. The last version of
this software was able to do a lot more in the same period of time. I
realise this most likely a client software issue but was hoping it may
be obvious whether Mapnik is spending too much time with Postgres.
Unfortunately I may just have to try again to build Mapnik from source
so that I can get debugging/profiling output, etc. -- I was hoping to
avoid it because it is quite painful.
