[Gluster-devel] fio libgfapi engine available

[Huamin Chen]

Hi team,

I am pleased to make available a preliminary drop of fio libgfapi engine. The idea is to investigate how much performance benefit that libgfapi can provide over FUSE. Per my initial testing, I see some positive results using libgfapi.

Please find the repository at https://github.com/rootfs/fio

In this drop, the gfapi engine is only capable of sync read/write operations, I am planning to make async IO available in the next drop.

To make the new engine, you have to have glusterfs-api-devel package installed. The following command line illustrates a simple test, where vol is the gluster volume, bd-brick is the gluster brick name.

fio --rw=randwrite --bs=4k --size=10G --runtime=60 --numjobs=1 --group_reporting --name=/fio_test --ioengine=gfapi --volume=vol --brick=bd-brick

Happy testing,

HC
