Well with only 64 Mb of RAM I have a document that needs 6 minutes to get compiled through LaTeX and when the 128 Mb are activated and the LaTeX job is probably running in the upper 64 Mb it takes more than 7 mn 30 s to get it compiled. I can tell there is a major slowdown and cache problem here:-( Anyway, as suggested in the mailing list I'll try to find the kernel patch for 2.1.xxx that allows me to do swapping those upper 64 Mb of RAM.
