I'll attach a copy, but it likely will be only marginally useful without the kernel source changes I've made as well. It's also been tuned to the hardware configuration - especially the amount of RAM, 256MB, and may not work correctly on machines with less memory. Handling 650 users is a difficult thing to do. :-) Over the past 12 months, I've turned many of the tweaks into config-file controllable things and have been slowly trickling them into the main (-current) source tree. Wcarchive has proven to be a good place to expose stress related bugs and performance problems. -DG David Greenman Core Team/Principal Architect, The FreeBSD Project # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # $Id: GENERIC,v 1.41 1995/04/10 19:13:51 phk Exp $ # machine "i386" cpu "I586_CPU" ident WCARCHIVE maxusers 300 options INET #InterNETworking options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options "SCSI_DELAY=10" #Be pessimistic about Joe SCSI device options UCONSOLE #Allow users to grab the console options DDB options "NMBCLUSTERS=8192" options KTRACE options "MAXMEM=262144" options DODUMP options "TCBHASHSIZE=1024" options AHC_TAGENABLE options "AUTO_EOI_1" config kernel root on sd0 dumps on sd0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 disk fd1 at fdc0 drive 1 #controller ncr0 # The three PCI 2940 controllers controller ahc0 controller ahc1 controller ahc2 controller ahc3 controller ahc4 controller scbus0 at ahc0 controller scbus1 at ahc1 controller scbus2 at ahc4 device sd0 device st0 #device cd0 disk sd0 at scbus0 target 0 disk sd1 at scbus0 target 1 disk sd2 at scbus0 target 2 disk sd3 at scbus0 target 3 disk sd4 at scbus0 target 4 disk sd5 at scbus0 target 5 disk sd6 at scbus0 target 6 disk sd10 at scbus1 target 0 disk sd11 at scbus1 target 1 disk sd12 at scbus1 target 2 disk sd13 at scbus1 target 3 disk sd14 at scbus1 target 4 disk sd15 at scbus1 target 5 disk sd16 at scbus1 target 6 disk sd20 at scbus2 target 0 disk sd21 at scbus2 target 1 disk sd22 at scbus2 target 2 disk sd23 at scbus2 target 3 disk sd24 at scbus2 target 4 disk sd25 at scbus2 target 5 disk sd26 at scbus2 target 6 # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr device npx0 at isa? port "IO_NPX" irq 13 vector npxintr device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr device de0 #device ed0 at isa? port 0x280 net irq 5 iomem 0xd8000 vector edintr pseudo-device loop pseudo-device ether pseudo-device log pseudo-device pty 32 pseudo-device speaker pseudo-device snp 3
