Re: Bandwidth limit how do I detect.

Well, currently there's a problem in bw-limiting that makes this possible
to detect:

If a single client has several conections through the proxy, and the first
of these is able to saturate allocated bandwidth, the proxy doesn't split
available bandwidth evenly between these connections. First connection gets
all and nothing is left over for the other ones.

So if you first start a download of some huge file from a site near the
proxy (so this single download can saturate your bandwidth), further
requests will get hardly any bandwidth until the first one finishes.

If you download 3 large files from the same site, you'll see for example
one file with 10kB/sec and two files with <1kB/sec.

Careful: you'll only see these effects for cache misses - anything found in
the cache will always be delivered at full speed.

Bye, Martin
