Re: Recent -current Performance Drop?
I turned off the malloc AJ flags, via malloc.conf. It improved 'make world' by something like 17% == mean_aj/mean_AJ. Make World Statistics -current SMP, 2xP133, 96MB RAM, IBM Superstor 9G disk.

Note it's a large performance hit when you tend to run a LOT of stuff and always dig into swap very quickly.

Re: Recent -current Performance Drop?
Actually in the past week or two I have seen a make buildworld drop from 205-210 minutes to 180-190 minutes. But I would be more inclined to attribute that to changes in the source tree itself, not performance. On Tue, 11 Jul 2000, Thomas D.

>I seem to see somewhat of a performance drop in the past week. You should have read the commit messages :-) I enabled malloc flags AJ by default, this has a performance cost. It will be turned off for releases of course. It has already exposed on bug (see peters commit).

Re: Recent -current Performance Drop?
phk turned on some extra malloc options by default that a) catch more bugs b) make it slower. I hope you are reading cvs-all when you are using -current. On Tue, 11 Jul 2000, Thomas D.
