HTTP traffic slow when access via LTM

Thanks all. I did some googling prior to posting and saw the suggestions to disable nagle so i had done that prior to posting.

As for resources: Instance type m3.xlarge (4 vCPU, 15G ram, SSD's with provisioned 3000 iops) There is little to no traffic on this instance currently as i am the only one using it for testing purposes. Current system Stats 0% CPU 14% Mem

Config and network design Located in AWS VPC 1 management + 2 Self IP's Elastic IP --> External VLAN Self IP (10.0.10.250) --> VS --> Internal VLAN Self IP (10.0.8.253) --> nodes (10.0.6/7.0/24) Routes 0.0.0.0 to external VLAN 10.0.0.0/16 to internal VLAN via 10.0.8.1 (default gateway)

As the network design in very simple there doesnt appear to be unwanted hops route wise.

Test VS.
