Hi,
I am using an EMC Isilon (NAS - SMB 2.1) with both OS Windows 2008R2 and 2012R2.
When a file is being written to a shared drive from 2008R2 and someone needs to read it, 2008R2 hangs for ~60 seconds until it can be readable, but 2012R2 is practically instant.
If the file is being written to the shared drive from 2012R2, all read of this file from 2008R2 and 2012R2 are instant.
I tried few things seen in forums everywhere:
- Disable Oplock on Windows 2008R2 or Storage (Performance is decreased when doing so)
- Disable TCP Offload - Didn't do anything.
What i don't understand and need help in, is to know why 2012R2 out of the box works perfectly fine and 2008R2 has issues and what can i do to improve 2008R2?
I need to continue supporting my clients that own 2008R2, so any suggestions and help would be appreciated.
Thanks.
