Hi Ron, 

To test Hyperscale performance you can leverage FIO (a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user).

• Test Read Performance to Gluster 
  • groot@win-hs1 ~]# fio --name=(name of the job) --rw=(Type of I/O pattern) --direct=1 --ioengine=libaio --bs=(buffer size) --numjobs=(number of process to run) --size=(size of the file to be created) --runtime=(t --group_reporting --iodepth=(Number of I/O units to keep in flight against the file)
    • Example (note - all parameters are tunable):
      • For writes you should change the "--rw=" to one of the following 
        • --rw=read (sequential read)
        • --rw=randread (random reads)
        • --rw=rw (mixed sequential reads and writes)
        • --rw=randrw (Mixed random reads and writes)
      • # fio --name=seqread --rw=read --direct=1 --ioengine=libaio --bs=32k --numjobs=1 --size=1G --runtime=600 --group_reporting --iodepth=8
• Test Write Performance to Gluster 
  • oroot@win-hs1 ~]# fio --name=(name of the job) --rw=(Type of I/O pattern) --direct=1 --ioengine=libaio --bs=(buffer size) --numjobs=(number of process to run) --size=(size of the file to be created) --runtime=(t --group_reporting --iodepth=(Number of I/O units to keep in flight against the file)
    • Example (note - all parameters are tunable):
      • For writes you should change the "--rw=" to one of the following 
        • --rw=write (sequential writes)
        • --rw=randwrite (random writes)
        • --rw=rw (mixed sequential reads and writes)
        • --rw=randrw (Mixed random reads and writes)
      • # fio --name=random_read_writes --rw=randrw --direct=1 --ioengine=libaio --bs=32k --numjobs=1 --size=1G --runtime=600 --group_reporting --iodepth=8

 Since gluster writes data over the network, its also important to test network performance. You can follow these instructions for network tests.

I hope this was useful
