Well, CPU usage would be ok, but i feel that it is using excessive CPU usage,
and furthermore i feel that even 4 processes are using *all* the CPU power
available, and it seems to be also linked with the available memory.

I have had at least 3-4 such reports, and am asking Ingo to also mention his
experience with this. All those i know have disabled swf-player to solve the
issue.

Do you have an idea of why so much cpu power is used ? And maybe some kind of
control option, ideally set at install time depending on the number of
processors, would help in this case ?

Well, I think that having the machine crawl to uselessness is also a problem.
No other package i run does that on my hardware.

Err, i also mentioned having to kill those processes by hand in the original
bug report, didn't i ? Well, they where not limited to 5 back then though.

BTW, would it be possible to make the number of helper processes a config
option that can be changed, so we can better experiment and look after these.

Gladly, what kind of information do you need in addition on what we have
already ? Basically 4 processes eat all cpu usage (and probably a big chunk of
memory too), and stay even when you kill the browser, and have to be killed by
hand. 

Friendly,
