nekrosoft13 Posted September 30, 2003 Share Posted September 30, 2003 what is the actual gigabit ethernet speed? some one told me that it wasn't 1000mbits/s, something close to 800-900mbits/s is that true? Link to comment Share on other sites More sharing options...

MxxCon Posted September 30, 2003 Share Posted September 30, 2003 you were told correct. it's theoretical "raw" bandwidth. actual data rate on a good setup is 800-900mbits/s. as you know maximum ethernet transmit unit is 1500bytes. out of those 42bytes are used for tcp/ip header, so it's already impossible to achieve 1gig/sec.. to that add possible loss of packets, possible lack of cpu to handle such fast transfers, possible lack of I/O, etc, etc, etc Link to comment Share on other sites More sharing options...
Ritalin Posted September 30, 2003 Share Posted September 30, 2003 i guess it sounds logical... Link to comment Share on other sites More sharing options...
Steven Posted September 30, 2003 Share Posted September 30, 2003 Intel CSA Gigabit Fixes these PCI limitations. Link to comment Share on other sites More sharing options...
jwkuipers Posted September 30, 2003 Share Posted September 30, 2003 Yes Intel CSA does fix these limatations, but no hard drive can hit 125MB/sec (which is around what gigabit ethernet can hit). Allthough if you get maybe a rocket drive from http://www.cenatek.com/ you might be able to get close to 1gb a sec. I tested one of those drive, and got 100MB/sec off of it over standard pci. At the time I did not have two computers with gigabit, so I could not test the throughput. Link to comment Share on other sites More sharing options...
nekrosoft13 Posted September 30, 2003 Author Share Posted September 30, 2003 i got a onboard Intel CSA Gibabit how high can that go? Link to comment Share on other sites More sharing options...
MxxCon Posted September 30, 2003 Share Posted September 30, 2003 900.000001mbit :D Link to comment Share on other sites More sharing options...
Steven Posted September 30, 2003 Share Posted September 30, 2003 i got a onboard Intel CSA Gibabit how high can that go? it can reach the 1Gb speed. since its a dedicated 266Mb/s BUS. Link to comment Share on other sites More sharing options...
