Hi!

Yes. We try to use MassiveCache and fill settings as Tomas recommended. But it didn't help much. We made higher RAM from 8 to 32 Gb, but it didn't help either.
If You have solutions or suggestions to make this Server work faster and users would not interfere with each other, we would appreciate it.

Maybe there are suggestions on how to re-program huge import processes to work on other cores, so it do not interfere with users on other companies.

And maybe there is a faster way to import big xml files? Because, the main time is taken while this file is being opened.
