[OpenIndiana-discuss] Firefox cpu load / sluggishness

[Aurélien Larcher]

Hi,
i just came across this:

https://bugzilla.mozilla.org/show_bug.cgi?id=508427

The advice is to set layout.frame_rate to a lower value than the default 60
(-1).
The same applies to Thunderbird.

dtruss shows for 30sec:

// layout.frame_rate = 24

It seems to lower pollsys count as advertized (if I understood well).

How does this look for you?

Kind regards
