Great, that gives hope...
Tec, my own online computer has merely 256MB RAM (8MB for video), but running on 98SE it's still usable - mostly... Restarts are a pain, but necessary every few days.
What does help performance greatly is a RAM cleaner, there are tons out there, mine is ancient RAM Def XT, great on 98SE. You might need another, no idea.
What does help me ENORMously, for performance and safety alike, is to block javascript! And embedded objects, and image animations, and DOM storage, and ads... Have you discovered already KMs great privacy toolbar? It has buttons for most of that stuff to just quickly toggle on-off when needed! Added a few more toggles myself.
