Package: iceweasel
Version: 31.7.0esr-1~deb8u1
Severity: important
Dear Maintainer,
I just spent about an hour writing up this problem, just to have
reportbug trash the report when attempting to email it. Here is the
short version.
Iceweasel seems to slow down after using it for a while. Seems to be
correlated with how much data is transferred. Shows up on www.cnn.com
when viewing pages with embedded video, etc. The problem can be
reproduced by this:
Use iceweasel to access www.speedof.me, and run the speed test multiple
times. Each successive run is slower. In my environment, I get about
70Mb/sec on the first run, decreasing to about 4 Mb/sec after running
the test five times. Running the same procedure with Chromium, each test
results in approximately the same network speed, regardless of how many
times the test is run.
When iceweasel is in slow mode, browser operation is sluggish. When
hovering over menu items like "tools", it takes almost a second for the
dropdown menu to appear. Typing in the address bar is like typing with a
300 baud modem connection.
Closing Iceweasel, or going to www.google.com and then returning to
www.speedof.me, seems to reset some internal state in Iceweasel, and the
test again runs quickly the first time, with decreasing speeds on each
successive run. However, going to www.google.com in a separate tab does
not have the resetting effect, it is necessary to completely leave the
speedof.me site for the reset to take place. Clearing the application
cache and cookies does not cause the reset to happen, either.
Running Firefox and Chromium on a Windows 7 PC has a similar result.
