TCP buffer

na arnesovi strani sem izvajal speedtest in del rezultata se glasi : This connection is receiver limited 14.84% of the time.
Increasing the the client's receive buffer (63.0 KB) will improve performance

torej se je morda že kdo soočil s tem oz. ali kdo ve kako bi povečal buffer?

test je na tej strani http://ndt.arnes.si/...tnx
