Times vary - going direct to an Apache or IIS server, we are seeing a download of 25MB of around 4-5 secs. When we put the same server behind and F5, more like 40-50 secs.

 

 

We have toy'ed with the TCP profiles. On some vip's changed some values and improved the speed to 20 secs...but its still not like for like.

 

 

Before we start playing around with the TCP profile, I wanted to clarify what I was doing on here to see if anyone had experienced similar. For all we know, we could improve larger file speeds - but degrade smaller!

 

 

I'll get my network people here to dump when I am downloading....as you said, there could be evidence here.

 

 

Many Thanks - Greg
