Re: Firefox Running Slow in Linux



The problems with FireFox "beeing slow" has two different reaons:

1.) FireFox UI is slow / Scrolling is slow:
Your video driver does not accalerated XRender well, or is slow for
other reaons. (While scrolling and running top, is FireFox eating all
the CPU or Xorg?)
FireFox just sends drawing commands to the X-Server, if the drivers
are broken its not FireFox fault.

2.) FireFox takes long to load / close:
FireFox does exactly the same on Windows as well as on Linux, but Ext3
completly dies when FireFox issues fflush commands to make sure all
files have been written appropriate.
