Subject: [Gluster-users] Performance degrade
Hi, I am looking for some help and advice from the community. I am
experiencing a performance degrade on my GlusterFS system after
upgrading from 2.09 to 3.05.
My setup has 2 clients and 2 storage servers configured in a
distributed / replicated setup over TCP Gigabit Ethernet.
My storage servers each has 36 x 1,5 TB SATA disks and a 4 core Intel
I7 processor with 6 GB RAM. I am runnig Ubuntu 9.04 with latest
My application is mainly a write once / read many app with small and
large files. Now it seems write performance has been degraded.
The GlusterFS servers are showing very high CPU usage. Around 200 %
for the glusterfsd process. RAM usage seems to be very low, only about
Should I be using, or not using, the performance translators I am using?
I need help and advice tuning my setup for better performance and
overall Gluster greatness.
Attached are examples of client and server vol files.
Thanks in advance.
