I entered the line export TIVOSH_POOLSIZE = 16777216 into my tivoweb.cfg file and I accessed tivoweb from school today and it didn't time out once. (Well, once when I was accessing HiGuide, but I don' really use that anyways.) The rest of the screens, including a few channel grids with 200-300 entries, loaded fine. (abit they loaded slow, but consider the shared connection at my school.) From what I've read, the line increases tivoweb's cache to 16 megs.
