Issue/Introduction
This KB lists the main items that can affect performance in a DX Platform setup
Environment
DX Platform 2x
Resolution
1) Storage should not be shared
There should be no load during a FIO or dbench-fio.sh test
Shared storage will have unpredictable performance results.
2) Main items that affects performance:
a) Actual storage (SSD drive) performance
As per DX Platform documentation, SSD is recommended.
Test IO throughput local to ensure storage is fast.
b) Network performance.
As per DX Platform documentation, it needs to be 10GBit connectivity. Easiest to verify is to use iperf3 tool (yum install iperf3)
On server: iperf3 -s -p 1111
On client: iperf3 -c SERVERIP -p 1111
c) CPU on NFS server and Client.
Server or client should not be overloaded and in case of VM it should not be experiencing CPU stealing (overcommit).
CPU has a big effect on network latencies as kernel schedule work for other processes as well.
d) Make sure NFS 4.1 is in-use
As per DX Platform documentation, NFS 4.1 version is recommended
