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.
If second results are also lower than `lowerLimit` the warning e-mail is send to recipients from the list (the `emails` parameter).
The speed benchmark is not performed until computers' load average is lower than `maxLoadAvg` (an optional parameter, default 0.75).
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
- Using the script with virtual machines can lead to large variations of speed results
- The speed benchmark is not performed until computers' load average is lower than `maxLoadAvg` (an optional parameter, default 0.75)
- The script sends e-mails using `mutt`; if `mutt` is not available it sends e-mails without attachments using `mail`; if both are not available it only prints a warning
The example usage with two test files, one e-mail address, and with an additional message:
