I am not sure what it is, so I do a search in Google and find More typical problem than TCP window size is Ethernet connection itself, for example one side thinks it has 100 Mb/s half duplex and the second side thinks that it has 100 Mb/s full duplex, which results in speeds around 10 - 100 KB/s. -- Rudolf Cejka <cejkar at fit.vutbr.cz> http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic
