 If a new commit is found it is compiled and a speed benchmark for this commit is performed.
 The results of the speed benchmark are compared to the previous results.
 If compression or decompression speed for one of zstd levels is lower than `lowerLimit` (an optional parameter, default 0.98) the speed benchmark is restarted.

 Additional remarks:
 - To be sure that speed results are accurate the script should be run on a "stable" target system with no other jobs running in parallel
