Dear Volodymyr,
your post was the opportunity to write a quick post about storage on Baobab that may be interesting for the users.
As you may understand from my post, it’s a bad idea to perform benchmarks yourself.
According to your post, you are reading the content of 178121 files to determine the performance of the storage. Please don’t.
If you really want to check the performance, there is a tool provided by BeeGFS: beegfs-ctl but it’s up to you to understand how to use it as it’s not intended to be useful for the enduser.
Best
