3 sec delay in transaction when going via F5
Hi All
Really appreciate this forum .
This time the issue is , we have migrated applications from Cisco ACE to F5 . While going via F5, the transaction for traffic takes 4 sec which is bad wrt to this application. But when it used to go via cisco ACE , it takes less than 1 sec. On F5, we are doing ssl offload, when we did a packet capture, the client hello is coming to F5 after 3 sec after the TCP handshake. The virtual server is standard type and tcp profile is with default settings. I am going to create a VS with out ssl offloading and on HTTP port and see if there is delay . Also in the packet capture from the client side, in the 3 sec before the client sends CLIENT HELLO, i see netbios stat query to F5 VIP , the client is accessing the F5 VIP , it is a soap request it is trying to send, Am not sure why it is doing a netbios stat query(Name query NBSTAT *<00><00><00><00><00><00><00><00><00><00><00><00><00><00><00>) to the F5 VIP,but it issues 3 times each takes 1 sec , and then when it fails after 3 times,it starts client hello .am not sure how this is related to the delay . We are taking a pcap from client side to check if netbios query is sent while client sends request to the cisco ACE VIP.if anybody has any idea of what is happening here , please do let me know?
