GS305v3 switch - Intermittently disconnects the connection, and slow speed.
Hi to all, I bought the GS305v3 Gigabit unmanaged switch in order to replace my 100Mbps fast ethernet 3com switch. I have install it on the same network but I have two different problems. I have a Ci...

This stinks (sorry my simple words). Gigabit Ethernet does work on a much higher frequencies than Fast Ethernet, and at about the double bandwidth. Assuming you talk of a jperf test between the two computers (one on the Cisco router LAN, on on the Netgear switch) and the traffic does travel this poor link. Clearly a cabling issue - not compatible for Gigbit Ethernet.

This can have different causes. The link issue described above can have a big impact, potentially repeated re-negotiation or at least massive errors on the GbE link. Another point is that computers can and will do some read- and write-caching from the mass storage - form a certain point (as there is typically no full SSD cache) the data is read and written from/to the effective storage media.
Not sure why you're getting the disconnects with the game. You could open a support ticket with netgear. These switches do have a 3 year warranty and 90 days of free support from netgear.
in terms of your speeds, are you sure its mbps and not MBps? Mbps stands for Megabits per second, while MBps stands for Megabytes per second. 113 MBps is 904 mbps. which would be equivelant of your gigabit connection. A lot of time you can transfer at full speed until you've saturated your cache and then it drops to the speeds of your hard drive or ssd.
You put that jperf won't get you past 95mbps but a file transfer will hit 113mbps. So just wanting to make sure you're looking at it correctly.
