Message-ID: <508E8C1C.4020605@gmail.com> (raw)
Hi,
Kindly guide me how to improve performance on the cluster which consist
of 5 dedicated servers:
- ceph.conf: http://pastebin.com/hT3qEhUF
- file system on all drives is ext4
- mount options "user_xattr"
- each server has :
CPU:Intel® Xeon® Processor E5335(8M Cache, 2.00 GHz, 1333 MHz FSB) x2
MEM: 4Gb DDR2
- 1Gb network
Simple test:
mounted as ceph
root@client1:/mnt/mycephfs# time find . | wc -l
83932
real 17m55.399s
user 0m0.152s
sys 0m1.528s
on 1 HDD:
root@client1:/home# time find . | wc -l
83932
real 0m55.399s
user 0m0.152s
sys 0m1.528s
Please help me to find out the issue. Thanks.
