1. What problem/issue/behavior are you having trouble with? What do you expect to see?

Hi Team,

We have rhel 6.6 server and we we are seeing to much delay on server and we are unable to disable it on the server.

[root@Server~]# netstat -s|grep dela
249698 delayed acks sent
20 delayed acks further delayed because of locked socket
[root@Server~]#

2. Where are you experiencing the behavior? What environment?

We are experiencing while reading data, writing is fine but its too slow while reading the data on mounted EMC storage

Red Hat Enterprise Linux Server release 6.6 (Santiago)

4. When does the behavior occur? Frequently? Repeatedly? At certain times?

We have observed this behavior on very first time

We need urgent help on this, any help highly appreciated on this.

Thanks
Sunil
