Comment (by SimonKing):
One remark on the reliability of the startup_time plugin:
With the previous version of the patches, we had:
{{{
-With 25% confidence, startup time increased by at least 0.25%
-With 44% confidence, startup time increased by at least 0.1%
+With 82% confidence, startup time decreased by at least 0.5%
+With 97% confidence, startup time decreased by at least 0.25%
+With 99.3% confidence, startup time decreased by at least 0.1%
}}}
Hence, we had a significant speed-up of 0.25% of startup time.
With the current version of the patches (which only differ in the removal
of one doc test, but there is no change in the code!!), we have
{{{
-With 25% confidence, startup time increased by at least 0.25%
-With 44% confidence, startup time increased by at least 0.1%
+With 85% confidence, startup time increased by at least 0.5%
+With 98% confidence, startup time increased by at least 0.25%
+With 99.4% confidence, startup time increased by at least 0.1%
}}}
Hence, we have a significant slow-down of 0.25% of startup time.
But since the code didn't change, perhaps it isn't significant, after all?
