If so, then I am very pleased indeed! Yeah, that's what I mean! Granted, this is just my workstation so I don't have that many interrupts, but I often have a lot of network traffic, and ATA drives generate quite a lot of interrupts during make world ;-) Bye, Andrea -- Yes, I've heard of "decaf."

As John and Kris reminded me, the slowdown was because of this - should have checked again the archive, I remember it had been mentioned before.

When I say severe I mean make buildworld takes x3 longer. Do you have MUTEX_DEBUG in your kernel? Kris PGP signature

Hi John, every "recent" version I tried resulted in a slowdown so I didn't recompile very often; until tonight, I was still runninng a kernel from 20010214. Tonight I created a new kernel but I finally figured out I should take out most debugging options: options DDB # options WITNESS # options WITNESS_DDB # options MUTEX_DEBUG # options INVARIANT_SUPPORT # options INVARIANTS and now performance is very good, event with: kern.random.sys.harvest_ethernet: 1 kern.random.sys.harvest_point_to_point: 0 kern.random.sys.harvest_interrupt: 1 Later tonight (my locale) I saw a few other commits to ithreads and such, exp. your commit which should fix my issue with pccard (thanks a lot for that!), so later a will update again and start building kernels adding back the debugging options one at a time. I'll post the result. Bye, Andrea -- Actually, Microsoft is sort of a mixture between the Borg and the Ferengi.

U using SCSI? Nope, UDMA33 (IBM-DARA-20600 on IBM Thinkpad). Question: you built a world yesterday, but what world did you have BEFORE? I mean, what matters is the kernel/world which was running while you were compiling, was that recent (< 15 days old)? Are you seeing any lock reversal message?

I did not see any lock reversal messages. My config is pretty standard, let me know if you want a peek (the only "non-standard" bit is the fact that I'm running newcard, I doubt this would matter in this case).
