This is not an issue, just a report for your info. Below is the result of running the run_all_tests.sh script 4 times on my laptop -- Dell Precision 7530.

(This excludes MATLAB)

(weirdly if I run fortran test on its own, rather than in the context of the script, I generally get higher rate - ranging between 1.7 and 2 Gpair/sec)
