Description

Hi,

We've 24 OSTs load balanced between OSS1 and OSS2 Servers. We are getting a degrade in performance while 24 OSTs load balanced between OSS1/OSS2 and also all OSTs handled by OSS1 alone. But we could see 3X performance while OSS2 handles all of the OSTs.

I've attached the logs from both the nodes for your reference. Appreciate your help.
