Well yes and no. Not according to htop. Seamonkey is the resource hog; |
| 19 |
or using the most resources (40-60 %). Firefox is 1-4%. I keep both |
| 20 |
open with dozens of tabs. The sad thing is my (8)( core amd 8350 |
| 21 |
with 32 Gig of ram is barely using (1) core, unless I compile a |
| 22 |
big multi-thread package. What I do have is almost a full second of |
| 23 |
keyboard response latency. I can close both and the system is snappy |
| 24 |
on response. I open either one (FF or SM) and the 3 dozen or so tabs |
| 25 |
and it's back to keyboard lag; even though the resource utilization is |
| 26 |
scant (1-1.5 cores/8 and 5300/32093MB). |

Since the kernel dev folks have change so much over the last few years. |
| 30 |
I figure I need to take a long hard look at what is enabled in the kernel, |
| 31 |
and how resources are awakened or idle'd via some kernel-profiling. It's |
| 32 |
most likely some advanced power conservation feature(s) that need tweaking, |
| 33 |
is my best guess. |
| 34 |
|
| 35 |
I have a system with plenty of extra, expensive ram and idle cores should; |
| 36 |
it not be sluggish, uniless a big hog of a single threaded process |
| 37 |
is not being properly managed. |
| 38 |
|
| 39 |
Even when my browsers are not (actively) being use but open, I get |
| 40 |
the horrible sluggishness now; and I'm running lxde.......not kde. |
| 41 |
|
| 42 |
Sometimes I can hardly type it's so bad. I have always had lots of |
| 43 |
tabs open for years and not experienced this sort of lag. Minimal resource |
| 44 |
utilization, but horrible lag. |
| 45 |
|
| 46 |
I've installed and ran' sys-power/powertop and it has some interesting |
| 47 |
information; but theres still no conclusion as to what is causing |
| 48 |
this inherent systematic latency. I do suspect FF and SM and Thunderbird |
| 49 |
are part of the problem, but overal resource utilzation is well below 20% |
| 50 |
(ram and cores) all the time, except when compiling. |
