1097240 - Try out how shorter CC slices would work

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

Currently the slice time is 10ms, but I think we should try 5ms.
10ms dominates currently CC slice max times.

(Unlinking isn't incremental, so this doesn't affect to that.)

let's see what tryserver says. Need to look at also perf numbers.

Let's see what telemetry says about this.

Even if this wouldn't help with unlink slices, this should reduce marking slice, which means there is a chance that fewer frames are dropped during painting.
