Severe performance degradation (5x slower) between versions 375.26 and 367.48

Hi everyone,

One of our sysadmins accidentally installed version 375.26 off one of the official repos on our CentOS 7 servers, instead of our usual 367.48.

We noticed on those servers that performance on the most GPU intensive SQL queries (on SQream DB) went down by a factor of about 5. Meaning, we’d have queries running in 17 seconds before on 367.48, and would run 80 seconds on the newer 375.26 driver - which is 4.7x slower.

Has anyone else noticed this kind of behaviour?
