Not according to htop. Seamonkey is the resource hog; or using the most resources (40-60 %). Firefox is 1-4%. I keep both open with dozens of tabs. The sad thing is my (8)( core amd 8350 with 32 Gig of ram is barely using (1) core, unless I compile a big multi-thread package. What I do have is almost a full second of keyboard response latency. I can close both and the system is snappy on response. I open either one (FF or SM) and the 3 dozen or so tabs and it's back to keyboard lag; even though the resource utilization is scant (1-1.5 cores/8 and 5300/32093MB). Since the kernel dev folks have change so much over the last few years. I figure I need to take a long hard look at what is enabled in the kernel, and how resources are awakened or idle'd via some kernel-profiling. It's most likely some advanced power conservation feature(s) that need tweaking, is my best guess. I have a system with plenty of extra, expensive ram and idle cores should; it not be sluggish, uniless a big hog of a single threaded process is not being properly managed. Even when my browsers are not (actively) being use but open, I get the horrible sluggishness now; and I'm running lxde.......not kde. Sometimes I can hardly type it's so bad. I have always had lots of tabs open for years and not experienced this sort of lag. Minimal resource utilization, but horrible lag. I've installed and ran' sys-power/powertop and it has some interesting information; but theres still no conclusion as to what is causing this inherent systematic latency. I do suspect FF and SM and Thunderbird are part of the problem, but overal resource utilzation is well below 20% (ram and cores) all the time, except when compiling. hth, James
