Hello experts :)
I has small network with 5 PC, each with 1 GB NIC - two Intel(R) PRO/1000 build in motherboard, 3x Realtek (32 bits) NICs. When transfer between Intel(R) PRO/1000 I get about 20-30 MB/s, while when realtek 10-15 MB/s. Orginaly I transfer 1-10 GB files :)
I read many info how to increase speed and come to conlusion that "Jumbo Frames" can do this (with 9K is best). I check -
Intel(R) PRO/1000 support Jumbo Frames with adjustable size - 4K,9K,16K, Realtek has options - enable/disable of Jumbo Frames.
I set all and can
So I think that problem may be in swither. Does anyone know if 3COM OfficeConnect 5x10/100/1000 support jumbo frames ? I can NOT find more info about jumbo frames and 3COM officeconnect.
Here is link to be sure for wath swither I tolk.
