Are you using WiFi? That will slow your connection.
Does all your equipment support Gigabit LAN? Your network will run at
the speed of the slowest component. You can use Cat5 cable, but Cat5e
is better. When I was upgraded from 100Mbit/s to 200Mbit/s I knew this
machine had a 10/100 built in LAN card so I disabled it.
I first bought a PCI-E USB3 card and a USB3 Gigabit LAN device. I then
replaced it with a PCI Gigabit LAN card. I replaced my TP-LINK 5-way
10/100 switch with an 8-way Netgear Gigabit LAN switch. I could connect
directly to the PC at 210Mbit/s, but only 90Mbit/s through the switch.
I found a post in Netgear's forum from someone with a similar problem so
I concluded the switch was faulty.
I replaced it with a TP-LINK switch only to find the same problem. I
eventually realised I had set the LAN card in the PC to the default of
auto speed detection. Also I had a 1.5m Cat5 patch cable between the PC
and the switch. The patch cable was being auto-detected as only capable
of 100Mbit/s. I replaced the patch cable with Cat5e and set the LAN
card to force a 1000Mbit/s connection. It then worked as it should.
I hope this gives you some idea of where to look.
