Hi,
I'm still working on upgrading us to 1.12 and after upgrading the extensions, I'm noticing that the 1.12 upgrade still takes a lot longer to render a page. For ( $elapsed = $now - $wgRequestTime;) for 1.9, I usually see on average about 0.15 seconds to serve a page, while 1.12 I'm seeing more like 0.50 seconds, with both installations running on the same server and connected to the same DB server, etc.
Here are some of the functions I'm seeing take awhile in the profiler.

The full profile is here:

Any ideas? I've tried drilling down into finding out why some of these are taking a long time. replaceInternalLinks seems to take a long time sometimes because the LocalFile::loadFromDB DB select statement sometimes takes over 50ms, but it looks like our indices in the image table are fine.
