meaning that between *.2 and *.3 there is an increase of around one second which is pretty small compared to what you observed. I will let you decide what to do with this bug.

One more thing: after 2.1.3, is the perf machine rebooted? Experimentally, RP has observed that long uptimes may lead longer perf times, so it may be wise to reboot machines once in a time.</thetext>

&gt; what to do with this bug.

I will close this as not a bug
&gt; 
&gt; One more thing: after 2.1.3, is the perf machine rebooted? Experimentally,
&gt; RP has observed that long uptimes may lead longer perf times, so it may be
&gt; wise to reboot machines once in a time.

Yes that was the cause also observed on most recent releases, There is a plan already set to reboot machines on a regularly, now the numbers are more consistent.</thetext>
