OmniWeb is the top memory hog among web browsers, and that's a high bar indeed. With only a few pages open, Activity Monitor reports 250 MB of Real Memory. Safari 3 and Camino report "only" about 150 MB. This is but one example but is typical. Others may respond that Activity Monitor's memory reporting is unreliable and I would be happy to find a reliable report. But I do know that with OmniWeb running, I wait much more often for virtual memory swapping to happen when switching programs. I have used OmniWeb for a long time and I have complained to the developers about this problem. The Omni people are a first class organization and I don't want to give them (much) of a black eye, but maybe posting something publicly with jolt them to reality.
