Let's bring in the actual gpu people.. Dave/Jani/others - does any of
this sound familiar? Pavel says things have gotten much slower in
6.10: "something was very wrong with the performance, likely to do
with graphics"

To bisect it, he'd need some way to judge it reasonably well and
without too much of a bias.

See

for the original report.

Thinkpad X220 - which I assume means old intel integrated GPU - at
least one listing I found for that thing is  i5-2430M, with "Intel® HD
Graphics 3000".
