I find it really interesting that safari usually cause my swap memory to be increase significantly. In 3-4hours browsing with Safari I could average around 2GB of Swap used in activity monitor. Do you guys find this quite common for your system as well? In Lion, some or many of us are facing major sluggishness with safari and I am one of them that being forced to switch to another browser. I am using Google Chrome currently and interestingly enough Chrome hasn't increase my swap a single bit after browsing for hours! In apple own words: "Moving data from physical memory to disk is called paging out (or swapping out); moving data from disk to physical memory is called paging in (or swapping in) Extended periods of paging activity reduce performance significantly; such activity is sometimes called disk thrashing." At first I thought maybe I am due to upgrade my memory or something but since I swap to Chrome, the sluggishness in Lion is all gone. I still miss some of the feature in Safari but performance wise, Chrome appears to be much better than Safari. Anyone have further insight?
