Connection to Server through BigIP slow, connection from Servers VLAN OK: How to troubleshoot?
Is this the right forum, I'm not sure ..?
Configuration:
================
- BIgIP in the DMZ
- Server behind the BigIP running private address space
Server is made public through a virtual Server' Public IP
Server gets it's data from a client on private net through the private IP
Client (private net)->
input BigIP DMZ Interface ->
output BigIP Server VLAN Interface ->
Input Server Interface
Communication Client <-> Server is running through a Forwarding Virtual Server (under Virtual Servers), which is in Performance(Layer 4) Mode. See Attachment.
Problem description
================
Slow communication between Client / Server
Fast Communication from this client if in Server' VLAN (NOT GOING THROUGH THE BIG-IP)
Wireshark stream Client<->Server shows no errors.
We measured the connectivity with iperf, here are the results
C:\iperf>iperf -t 60 -c 10.136.228.3
------------------------------------------------------------
Client connecting to 10.136.228.3, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1908] local 10.136.172.202 port 4643 connected with 10.136.228.3 port 5001
[ ID] Interval Transfer Bandwidth
[1908] 0.0-60.0 sec 181 MBytes 25.3 Mbits/sec
25 Mbit/s are not bad, without BigIP there are 80 Mbit.
There are some more profiles in the Forwarding Servers's configuration, may be they could help?
