Description

Before retained layers (bug 564991) landed Tscroll on Linux produced erratic
results with frequent time outs.  Bug 555352 comment 35 discusses the erratic
nature of results.  This is the last 32-bit fed 12 result: (Note that the median used in avgmedian means that the times that are 27x slower than typical are ignored.)

Since retained layers landed, results (7 runs to date) have been much more
consistent with no time outs yet.  This is the first fed 12 result with
retained layers (The next half dozen are similar.):

The mean of these numbers is probably not too different from those without
retained layers, but the variance is much smaller.

I don't actually know what these numbers mean.  I'm suspicious of results that were in the majority of cases very close to 10ms for each of the tests.

That's probably 10 seconds (not ms), actually.

For reference, here are some results on other platforms:
