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 updates. 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 148 MB. 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.
