just upgraded the apartment to gigabit

bought a linksys gigabit switch. 4 computer is hooked up to it. The average speed i'm getting is only abour 30MB/sec. Would upgrading the network cable increase the speed? We only have cat5 in the apartment. No cat5e.

I think the best you'll get with gigabit is around ~450Mbps

would it help if i upgrade the cable to cat5e?

I believe CAT5 is rated at 100Mbps. 5e at 150Mbps. 6 at 1000Mbps.

It varies tremendously from setup to setup. One thing is certain: the network pipe is no longer the bottleneck!

I've seen FTP tranfers of close to 1000Mbit within our cloud so it is indeed possible. PCI-X 133MHz equipped computers on both ends goes a long way.

Look at it this way: If you're getting 240Mbps speeds, it's at least 3x improvement you were getting with your old 10/100 setup. That kind of increase is nothing to sneeze at!

Cheers!

i was hoping we can get at least 40-50MB sec

If your computers have 512MB (1024 or more works even better!) physical memory, enabling large system cache can help out here. You should see highest numbers when transferring large, single files. Small files will cut down your average rate tremendously unless you have some serious storage on both ends.

Cheers!
 
How is your wiring set up? Did you make the cables, or are they factory? Bad wiring can kill your transfer speeds.
 
are you using a crappy protocol like windows network file copy or a good one like FTP to measure?

nic are not onboard. But it's one of those realtek chip.

I'm using windows network file copy. Using dumeter to measure the speed. And i'm transfering dvd iso across the network.

Well then you'd be limited by the PCI bus, no?
 
5e can do 1000mbps but only over a short distance (not sure what it is). cat 6 will do 1000mpbs over the full 100 meters. However, as other people have said, you'll hit other limiting factors very soon, even if you do upgrade the cables.
 
What does your CPU utilisation look like when copying large files? Some adapters/chipsets have extremely high CPU utilisation!

Cheers!
