Web access issue from web browsers

Hello

We have an issue with our client, they try to access a website from Google Chrome and the page does not load or it takes too long, when they use Internet Explorer it works fine. We tried changing the TCP profile and use the tcp profile by default.

ltm profile tcp apm-forwarding-client-tcp { 
ack-on-push enabled
app-service none
close-wait-timeout 5
defaults-from tcp
deferred-accept disabled
delayed-acks enabled
ecn disabled
fin-wait-timeout 5
idle-timeout 300
keep-alive-interval 60
limited-transmit enabled
max-retrans 8
nagle enabled
proxy-buffer-high 49152
proxy-buffer-low 32768
receive-window-size 65535
reset-on-timeout enabled
selective-acks enabled
send-buffer-size 131072
slow-start disabled
syn-max-retrans 3
time-wait-recycle enabled
time-wait-timeout 2000
timestamps enabled

Is there something in the tcp profile that can be changed to optimized the traffic?

Regards

application delivery

    Hi,

     

    I suggest you to analyse the traffic with tcpdump to understand the cause of this slowdown before trying to tune your tcpprofile. If it works well with IE, then a simple comparison will be enough to clarify the problem normally.
