fast network peroformance
hello all,
i have 100MB/sec network adapter on debian squeeze server and when i download from it i only got 10MB/sec how i can make it fastest ?? thank you ... |
i made
ethtool eth0 ethtool -s eth0 duplex full speed 100 autoneg off mii-tool eth0 mii-tool eth0 -F 100 but the same result |
i changed the cable between debian server and windows pc and the same also

sudo /sbin/ethtool eth0 |
It seems the NIC is of 100 Mb speed. So the 10MB speed you are getting is correct. Note the difference between upper case B and small case b

root@debian:~# /sbin/ethtool eth0

it is 10MB/sec in download manager
between my windows laptop and my debian server is only 1meter utp cable |
Your numbers are correct and nothing is wrong. The network adapters are connected with 100 Megabit/sec and your download manager is showing you a transfer rate of 10 MegaByte/sec. On byte contains 8 Bit, so the theoretical maximum (that never will be reached) for a 100 Mb/sec connection is 12.5 MB/sec and your transfer rate of 10 MB/sec is pretty normal.
|
and the maximum network cards speed is 1000MB that mean if i replace it the maximum download rate i will get is 100Mb/sec ??
is that right ? thank you :) |
If both network cards support 1000Mb/sec you should get a transfer rate of around 100MB/sec, as long as the harddisk in the delivering computer is fast enough to handle that and the disk in the receiving computer can store at this rate (or has sufficient amount of memory to cache the data).

Also if server and laptop are connected via hub/switch. Still, technically the speed depends on the speed of that hub or switch |
thank you very much TobiSGD & KinnowGrower
