A page fault is not a bad thing, it is merely an indicator from the CPU to the kernel that the page you want to refer to, the next page of executable data of the application you are running, is not in memory [yet]. The CPU causes a page fault and the kernel pages in the part(s) of the application to memory and then resumes operation, now being able to refer to the appropriate page.

Lots of page faults
I have a fairly recent CURRENT: FreeBSD kapran.bitmcnit.bryansk.su 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Sat Dec 30 12:41:53 MSK 2000 [EMAIL PROTECTED]:/usr/src/sys/compile/KAPRAN i386 And what I noticed is a massive slowdown when running make(1). It seems that I am going to finish a new `buildkernel' in a millennium or two. Additional symptoms include very high system CPU state percentage and a lot of page faults. vmstat(8) shows something like (while building world): procs memory pagedisks faults cpu r b w avm fre flt re pi po fr sr ad0 ac0 in sy cs us sy id 2 0 0 24216 8444 235 1 1 0 215 23 0 0 810 805 213 15 43 42 2 0 0 23776 8508 356 0 0 0 356 0 16 0 296 879 216 18 82 1 2 0 0 24252 8232 382 0 0 0 313 0 12 0 299 987 240 21 79 0 2 0 0 23664 8528 328 0 0 0 407 0 11 0 289 711 216 9 91 0 2 0 0 23816 8424 314 0 0 0 304 0 7 0 285 890 209 21 75 5 2 0 0 23792 8440 362 0 0 0 338 0 12 0 292 979 222 24 76 0 2 0 0 24284 8144 372 0 0 0 285 0 12 0 291 981 227 24 74 2 4 0 0 22724 8964 140 0 0 0 401 0 71 0 363 463 340 2 62 36 2 1 0 22392 8472 429 0 0 0 279 0 11 0 297 834 215 17 82 2 4 0 0 22628 8312 334 0 0 0 297 0 2 0 286 869 213 15 85 0 From time to time I get a core dump from `cc1' or `cpp' or even `as' too.
