There are also some other issues (wrt locking and probably some other stuff) but they are bearable. I am running a PII 400 with 64 MB with CURRENT, it mighn't be the fastest now, but at least it works. I have been stresstesting the damn thing (as in, run lots of (relatively) useless services on there like icecast, and more ;-) and it is still holding. So far so good. The performance is low? Didn't notice that (but do keep in mind I'm happy with very little :-). It's not even buckling under a constant load avg of between 1.something and 3.something and 200+ procs running at all times... No dataloss yet. Very good. [snip] > I'm just looking for a basic idea of what other people have been > seeing for performance when they run current. My performance is okay from what I expect of it. Of course I have DDB, INVARIANTS and WITNESS options on (to provide better info for the developers when it crashes for some unexplainable reason). If you are planning to do 'production' (mind the quotes) stuff with CURRENT, I suggest you could strip those. But beware, you are on the bleeding edge here :-) Cheers, Emiel -- The problem with the gene pool is that there is no lifeguard.
