Re: Rate limiting with "tc"?

Both rsync and wget offer working rate-limiting in userspace, why is

I cannot speak to can/cannot do inbound throttling in tc, but will
point-out that when a receiver does rate limiting above the socket
layer he may induce some behavoiurs in TCP (eg zero window probing)
which are not _normally_ seen in a transfer, nor in a situation when
the rate limiting is implemented _below_ TCP.

It may not matter for rsync and wget in and of themselves, but it can
be an issue if it is used in say load generators for networked server
benchmarking.
