If I recall correctly, I did hit similar issues when testing sage. Parallelism or any additional running processes during testing may have negative impact on timings. (e.g memory cache is shared between several applications) . As far as I know for testing the default is to use 3 parallel threads, see https://wiki.sagemath.org/buildbot Set it to 1 and see if the problem remains, run only one patchbot. Please report your findings.
