Halls of Heroes

I allways enter the match like 1 or 1 and half mins later.
My comp is Intel (R) Pentium (R)4 CPU 1700MHz 1.69 GHz, and 256 MB of random access memory.
I want to be able to enter areas like Ascalon without having to wait 1 min, or enter guild battle without having to wait 1 min.
What should I do?

Get another 256MB module, totaling 512MB RAM. That is a start.

Another is to do disk defrag, close all open progs, etc.
