NimbostratusConnection 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

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?

rkra_77787I do no have a 80 Mbps dump, just the iperf information.
Here is a iperf from my client to another location (same Bigip, same server behind), this is "55 Mbps only", there is a 4 ms Leased Line in between.
But much better then from my local site an 29 Mbps only:
C:\iperf>iperf -c 10.172.228.2 -t 10
