Git commit 48e1c0cffc04aae86338b68a6ae32b92db458758 by Dmitry Kazakov.
Committed on 11/05/2017 at 11:38.
Pushed by dkazakov into branch 'kazakov/cs-registry-rewrite'.

Disable tile data pool

It looks like at least in some circumstances it can make rendering of
the image 5-30% slower. I will disable it by default until further
details are investigated.

If you modified your performance settings, this auto-disabling will
not work. You should disable it manually by setting its size to 0%
in Preferences->Performace tab.

The testing, where the slowdown was registered, was done on 4k
image using KisProjectionBenchmark.
