| H A D | db_interface.c | diff 1246 Mon Mar 07 11:38:49 MST 1994 dg 1) "Pre-faulting" in of pages into process address space Eliminates vm_fault overhead on process startup and mmap referenced data for in-memory pages. (process startup time using in-memory segments *much* faster) 2) Even more efficient pmap code. Code partially cleaned up. More comments yet to follow. (generally more efficient pte management) 3) Pageout clustering ( in addition to the FreeBSD V1.1 pagein clustering.) (much faster paging performance on non-write behind disk subsystems, slightly faster performance on other systems.) 4) Slightly changed vm_pageout code for more efficiency and better statistics. Also, resist swapout a little more. (less likely to pageout a recently used page) 5) Slight improvement to the page table page trap efficiency. (generally faster system VM fault performance) 6) Defer creation of unnamed anonymous regions pager until needed. (speeds up shared memory bss creation) 7) Remove possible deadlock from swap_pager initialization. 8) Enhanced procfs to provide "vminfo" about vm objects and user pmaps. 9) Increased MCLSHIFT/MCLBYTES from 2K to 4K to improve net & socket performance and to prepare for things to come.
