No details, just a feeling. I've also experienced something similar when comparing System V and BSD: System V appears much slower. It's not borne out in performance testing, however. In the case of System V, I think it's because there's an almost imperceptible difference in the response at the keyboard, which gives you the feeling that it's slow. I don't know whether the impression you get with Linux and BSD has a similar background. > Are there any performance tweaks to increase my system's operating > speed?

For a change, though, I won't tell you to ask your question there, since it's not really related to -CURRENT. Oh, I didn't tell you more about the performance tweaks, did I? That's deliberate: first we need to know if any bottleneck exists, and if so, where. Then we can investigate tuning. So: where's the problem?
