CSS Command flow tcp-del-ack

[Sbutzek]

Hi,

i've found a Command in the Docs, that was addes in 7.50.103 to normal Command.

I read a thread, where Gilles wrote about a L5 rule, which should makes a delay of 200 ms.

I am not sure if i understand delayed ack right, but i think if disabled there should be no delay and if enabled there shoud one?

How can tell me what this feature exactly does and if it should be enabled or disabeld on L5 rules?

Best regards

Sven

Sven,

with L5 rule, if a request spans multiple packets, the CSS waits 200msec before ACKing a packet.

This is to save resources and wait in case the next packet was already sent by the client.

However, some client needs the ACK before sending the next packet, so the command disable this delay.

So we will always send the ACK and no longer wait for the next packet.

If your CSS is already being overloaded, you should not use this command, otherwise it is pretty safe and will increase performance seen from a client perspective.

Gilles.
