I have a server that used for high-frequency trading. That means that even 0.1 ms is important. I have up to 10 MBit/s data traffic. I need certain UDP ports to be opened because I receive data via multicast.
Now I don't know what should I do:
- just open ports that I need in Windows firewall and be secured but slow
just disable Windows firewall and be unsecured but fast
I am in LAN and server is not used for anything else than trading so it's probably OK to turn-of firewall
- From other hand how much delay firewall introduces? Probably this delays are not important for me?
