when I use ab to access the url,the hits counter changes,but no luck for browser, Besides this,I noticed that hits counter doesn't match number of request.

 

By the way,if I want to accelerate http/https traffic,what is the best practice to achieve this? Should I use AAM or only cache/compression part in LTM?

 

I read some articles,it seems if compression,LTM has specific hardware to do so for perfermance wise.

 

you are expert on F5 BIGIP,hope u can help me to achieve some cool stuff

 

but no luck for browser, Besides this,I noticed that hits counter doesn't match number of request.

 

is there any intermediate device? you may compare tcpdump on client and bigip.

i am not familiar with aam. hope somebody here can give some advise.

 

no intermediate device Besides this,I noticed that hits counter doesn't match number of request. :for example ,in your test ,u specify 10 requests,but why hits counter is 4.....
