Performance decrease using a S-NAT Pool
Hello F5 Experts,
I have a funny problem. I setup at my i4600 a VS (FastL4) what should balance traffic on TCP-Port 3299 to two SAP-Routers. When I do SNAT Automap it is performing quite well. Start SAP-GUI and I am immediately connected.
Because of many users are using SAP I created a S-NAT Pool what consists on round 25 IP addresses out of the same subnet range where the two SAP-Router Servers are placed in. The SNAT-Pool is bound to the VS. The LTM has one of it's VLAN interfaces also in the server vlan. I can ping that IP-addresses defined in the SNAT - pool from that SAP-Routers also without any problem. But when I now try connect with my SAP-GUI it either takes up to 10 seconds until I am connected to the SAPServer or it fails sometimes to connect...
So what cause that slow connect or that the connect fails many times?
