Cable Forum - View Single Post - messing about with internal wiring to improve ping and reduce jitter

I found that TCP Optimizer has a feature under advanced settings, gaming tweak called TCPNoDelay, & when Nagle's algorithm is disabled that I think helped reduce jitter;

Disabling "nagling" allows for very small packets to be transferred immediately without delay. Note that disabling Nagle's algorithm is only recommended for some games, and it may have negative impact on file transfers/throughput. The dafault state (Nagling enabled) improves performance by allowing several small packets to be combined together into a single, larger packet for more efficient transmission. While this improves overall performance and reduces TCP/IP overhead, it may briefly delay transmission of smaller packets. Keep in mind that disabling Nagle's algorithm may have some negative effect on file transfers, and can only help reduce delay in some games. source from: http://www.speedguide.net/articles/w...08-tweaks-2574

I have a 5m cat 5e cable from my pc to the superhub in a different room which is only just long enough, & 1Gbps link. Click the pingtest link below to see 0ms jitter which was taken at 7:30pm when traffic is busy.
