Hi.
I have upgraded my dedicated server and want to get optimum settings obviously
I have:

Processors: 2 x Xeon E5-2640v3 - 32cores
Memory: 197GB RAM
Disks: 4x 1TB SSDs
RAID: Hardware RAID 10
OS: CentOS 7

What would be the optimum settings please for:
gzip compression level (currently on default 6)
Number of pigz processes (currently on default 1 )

If there is anything else anywhere i should be checking i would be grateful for a point in the right direction!
many thanks
