Hello all!
One of my clients reported today that the internet access was slow and i
have delay_pool configured and qos in the linux server. I saw the

What i'm assuming is that rapidshare is breaking the file in small
chunks, so if i limit the download speed to 50k/s almost all this
"files" will arrive in 1 second and just after will download the next
chunk and so on, so the delay_pool is not effective in this case, am i
right?
Maybe. delay pools can be configure in many ways.
The pool class defines how many IPs are gathered into each pool /32,
/24, /16, username, etc.
Inside that each pool A/B pair can be considered to mean non-delayed
initial amount / delayed speed. Or another way commonly used by dialup
ISP the unliited bandwidth + capped overage speed.
The access lines define what requests get pooled and what skipped.
What can i do so as to avoid that this kind of downloads affects all
others? (Block rapidshare is not a solution because i can't block
anytihng, just control the speed)
You can set all traffic to delayed speed. Zero bytes cap with X
bytes/second overage.
Or you can use access + ACL on dstdomain .rapidshare.com into a unique
pool that does the above only for rapidshare sites.
