Slow koffice, SUSE 9.3

Hi, Koffice is unacceptably slow on my computer (2 x 1 GHz PIII, 1 GiB RAM) with SUSE Linux 9.3 professional. For instance it takes almost 1s just to draw a menu. The speed of OpenOffice.org is relatively OK, but Konqueror is also substantially slower than in 9.2. Has anybody find a way how to speed it up? I'll recompile some packages when I have time but I'm not sure it will fix the problem. -- A.M.
