Gigabit network LAN speeds

post #1 of 7
Thread Starter 
Hi

I was wondering how big a difference in speed a gigabit NIC and router would make when transfering data between computers on LAN. I'm interested because I frequently transfer 5+gb files to other computers in my house and it takes a REALLY long time. Right now, it takes 1 min to transfer 80mb of data so about 1.3MBps... Would switching to gigabit be faster? I'm using cat5e cables. I did a seach on google and could not find much information. Any help would be great!

Thanks

I would say yes, specially if moving around that large of files. Then again, I'm no network guru.

Here a list of things you should be certain to attain higher transfer speed:
- Gigabit-compatible NIC cards on every computer + network medium (router, such)
- Sufficient CPU power (somewhat fast because after data goes into NIC, it goes to CPU then hard drive, ~2.8Ghz Intel for example)
- Faster write/read speed for hard drives on every computers. (7200RPS preferably)
- Firewall and such should allow the transfer throughout.

Do you guys have any benchmarks? I'd like to know the actual numbers or a data rate. Correct me if i'm wrong, but when they say 1000Mbps, it's equal to 125MBps. By that idea, you could say 10/100 nic's transfer at 12.5mbps which is way faster then what I'm getting. Is that the upload or download speed they are talking about?

I transferred an 10GB folder (with small and large files) between a A64 2.4Ghz and a Intel P4 3.2Ghz through a 100mbps network and transfer rate stayed almost constant at 9.8MBps (compared to 12.5MBps which is max). Both computers equipped with 1000/100mbps NIC and WD SATA150 7200rpm.

Speed can vary little by hardware, but that's what you should expect.

Yes, in theory 125MBps. Also, home networks are not asynchronous. The upload/download speeds are equal (as far as the network is concerned... the hardware on one machine might make one way slower than the other as shajbot said.) The fact that you're using Cat5e is very good because it is rated at Gigabit speeds and won't be the slowdown in your network. Shorter runs, of course, are better. Either way, you should notice a massive increase moving to gigabit from something slower than 10/100.
