      I have an HP DL360 G6 with two Inel X5570 processor. I am using services: Snort, Squid, SquidGuard. Squid only for filtering, without caching on disk. Link 150/30, 150 users.
      Is it worth starting HT support in the processor? I can have 8C / 8T or 8C / 16T. Will it profit or not? It seems to me that Snort uses only one core :(

        That's a good question.  My gut says you wouldn't see a tangible difference either way with only a 150/30 link.  Maybe next time you need to reboot it for whatever reason, turn it on if you want to see for yourself.  Either way, that's probably quite a bit more processing horsepower than you can really use with your WAN connection.

          I've read somewhere that using HT increased latency. Can't remember where.

            hyperthreading effectively doubles your registers and halves your cache. whether that's a net win is entirely workload dependent. in the best case your latency and throughput will both increase.
