Dear All, Not sure that mIRC is used much these days, but I have a client's customer who shares files with people using mIRC client/server and the DCC protocol. It appears that DCC only uses a single TCP connection and that mIRC is not really designed for sending large file transfers, but this customer claims that the speed of his DCC has dropped hugely since moving to my client's internet service.
He is on a 1Gbps service and can speed test to well over 700Mbps symmetrical so that is fine, but he is claiming the internet service is not fit for purpose due to the DCC speeds. At one point the DCC speeds did increase quite dramatically after I reduced the CPU load on one of the core routers, but speeds have quickly gone back down to very low, but no change in resource or routing. I know there could be many other factors at play, but it is suspect that DCC is apparently fine on other provider networks, so does anyone have any experience of similar issues when using Mikrotik CCR routers? Something is nagging me! Best regards, Paul Bone
