Ok, on Windows 7 64 bit, I basically use Firefox to browse the web, with a DSL broadband connection.
Sometimes while surfing, I see the computer slows to a crawl for a few minutes and then goes all right again. At this time the Task Manager shows 98% memory usage with 3.9 GB being used out of 4 GB ram.
Today when this happened, I ended the Firefox process, and the usage instantly reverted back to normal 600 MB.
So whats happening?
