I first ran fio tests, and apparently my write speed is basically 90%, but my read speed is 40%. Here is my xml file:
<emulator>/usr/bin/qemu-system-x86_64</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source file='/mnt/raid_array/test_server/ubuntu20.04'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x0'>
</disk>
Fio:
fio --name=seqread --rw=read --direct=1 --ioengine=libaio --bs=1024k --numjobs=8 --size=1G --runtime=600 --group_reporting (sequential read)
Host: 327MB/s VM: 127MB/s This is only 39% of the Host speed.
fio --name=seqwrite --rw=write --direct=1 --ioengine=libaio --bs=1024k --numjobs=8 --size=2G --runtime=600 --group_reporting
Host:141MB/s VM: 114MB/s This is 80 percent of the host speed. This is acceptable, but I would like this to be higher too.
I am running BTRS raid 1, does anyone have any tips for speeding up my read speed?
