I just got a 1gbit switch and as far as i know my cables are cat5e. I have noticed when i trasnfer stuff between my pc and other 1gbit devices on my network i always get near exactly 0.5gbit or 500mbit. Does my pc have a dodgy or cheap 1gbit ethernet port or is it the switch?. Could it even be a simple setting somewhere i dont know about?
A lot of PCs do not have the ability to transfer at speeds reaching 1Gbps because their hard drives do not have a fast enough I/O speed or because they simply are not powerful enough in terms of CPU power or other components not being powerful enough, both the receiving computer and the transmitting computer.
If you are transferring data at around 0.5 Gigabits per second then you are definitely on a 1Gbps network.
For instance; we have been running a 1Gbps network over CAT6a since June 2009 and until June last year we were using a 1 Core, Intel Celeron 3.06GHz computer as a server (Whenever transferring files took place the CPU usage shot straight up to 100% - a tell tale sign that it was going as fast as it could).
We used to get around 65MB/s (520 Megabits per second) even though my PC has a 3GHz Quad Core and our cabling is CAT6a. When we upgraded to a more powerful server last year (Dell 1950) our speeds shot straight up to around the 100MB/s range with bursts of up to 110MB/s.
Remember that both the receiving device and the transmitting device need to be powerful enough to use 1Gbps otherwise you will suffer from reduced throughput.
What hard drives are you using? Are you using a network card? What are the specs of your devices? Do you have any programs on your PC which could be limiting throughput? Also how long is your cabling?
