Hello all, i am having problems with 10GB network speed through my XS508M switch.

Main network link is as follows...

Desktop PC: ASUS XG-C100C NIC
8m cat 7 cable
Switch Netgear GS110MX
20m cat 7 cable
Switch Netgear XS508M
2m Cat 7 cable
Server Intel X540-T2

With this network listed above i get 200-300mb/s file transfer speed (20%-30% of maximum throughput)

if I remove the XS508M from the network (PC-GS100M-Server) I can transfer at 1.1GB/s (close to 100% throughput)
or PC-server with a direct connection (25m cat 5e cable) I get 1.1GB/s.

So the XS508M must be the weak link.

Jumbo packets @ 9k, Recv Segment Coalescing ipv4 disabled

Any ideas? The switch should be good enough.

Can you test pc-25m cable- xs508m-server?

Just to be sure its the Switch and not the interconnect or the network hop

disabled jumbo frames on all adaptors and getting close to 500mb/s (50%) at times but the speed jumps around a bit.

Some malfunction in the switch to switch connection causing delays, eg stp problems or flow control or whatnot that primarily affects switch to switch and not switch to host.
