Every time it gives me such a message it says it's made an adjustment to the buffer size. The messages are very infrequent now, almost nonexistant, which leads me to believe FreeBSD has adjusted it's behavior/settings to match the type of load on my server (which I think is _very_ cool). However, I'm just wondering if I can set these settings manually in order to test settings. There's one thing I like about Windows which I haven't yet learned how to do with FreeBSD. In Windows, I can customize my box to use certain resources for certain things. For example, if I want to use 32 or 64 megs of memory for a disk cache, I can do that. You think, why the hell would you want to do that ? Well, sometimes I have machines, like file servers, which the most important thing they do is serve files. When I turn the disk caching up this high, the disk rarely gets touched, which saves on the life of my disk. The point is, I know what type of load my machine is going to have, and how much resources it has, and I want to be able to decide how much of X resource is used for Y task. I asked once how I could modify the disk cache/buffering settings for FreeBSD, and was basically told, don't touch, let FreeBSD handle it. I'm glad FreeBSD is intelligent enough to decide how to use my resources, but what if I feel that there's alot of memory free, like 95 megs, and I want to reduce the beating my hard drive is taking. Is there an option to do this ? I know of the MFS/tmp optimization and I've tried this out with mixed results.
