I have read that in 7-Current there are two schedulers. 4BSD - which, AFAIK, is a renamed new SMP scheduler, but i'm not sure ULE 7-current amd64 is actually seems to be VERY stable on hardware and software we use, so, we want to move it to production servers and want to get max perfomance from it for web hosting. As, as i know, scheduler is a very important thing when i comes to perfomance in havy loaded really multitasking system. We are having about 900 processes in about 20 jails. So, what is the difference between the two? Which seems to be better for hosting? Is ULE bugfree and stable enogh for this? -- Thank you in advance, Artem
