This is a 500mhz Blade 100 with a GENERIC minus WITNESS* kernel. -- -- David (obrien@FreeBSD.org) I have been rebuilding my dual cpu Ultra 60 occasionally, including several times after the gcc upgrade, and have not noticed a large slowdown. Here are some datapoints, maybe it will help discover where the problem lies if someone can try at least a similar build configuration. Notables in config and build are NOPROFILE=yes, no DEBUG=-g, no INVARIENTS*, no WITNESS*, SCHED_4BSD (sometimes I use ULE, but not in the past month), SMP, /etc/malloc.conf -> aj, make -j2 MAKE="make -j2" buildworld. I always cvsup before building if it is a new day. I can return more information or tests if anyone wants. Infact, I occasionally compile the samba port as a dirty benchmark, and the compile time dropped from ~9.5 minutes to 8 minutes between may and july 18. bw1.log:Script started on Sun Jun 8 17:16:52 2003 bw1.log:Script done on Sun Jun 8 19:36:52 2003 bw2.log:Script started on Wed Jun 11 22:51:51 2003 bw2.log:Script done on Thu Jun 12 00:54:38 2003 bw3.log:Script started on Fri Jun 13 18:26:45 2003 bw3.log:Script done on Fri Jun 13 20:18:21 2003 bw4.log:Script started on Tue Jun 17 18:45:08 2003 bw4.log:Script done on Tue Jun 17 20:34:12 2003 bw5.log:Script started on Wed Jun 18 17:44:28 2003 bw5.log:Script done on Wed Jun 18 19:33:28 2003 bw6.log:Script started on Tue Jun 24 18:28:54 2003 bw6.log:Script done on Tue Jun 24 20:17:47 2003 bw7.log:Script started on Tue Jul 1 18:25:01 2003 bw7.log:Script done on Tue Jul 1 20:57:22 2003 bw8.log:Script started on Wed Jul 2 19:59:14 2003 bw8.log:Script done on Wed Jul 2 22:46:29 2003 bw9.log:Script started on Fri Jul 4 10:15:08 2003 bw9.log:Script done on Fri Jul 4 13:04:01 2003 bw10.log:Script started on Wed Jul 16 19:24:34 2003 bw10.log:Script done on Wed Jul 16 21:02:10 2003 bw11.log:Script started on Thu Jul 17 17:23:07 2003 bw11.log:Script done on Thu Jul 17 19:00:30 2003 bw12.log:Script started on Thu Jul 17 19:35:37 2003 bw12.log:Script done on Thu Jul 17 21:13:46 2003 bw13.log:Script started on Thu Jul 17 23:53:55 2003 bw13.log:Script done on Fri Jul 18 03:10:21 2003 bw14.log:Script started on Sun Jul 27 12:03:38 2003 bw14.log:Script done on Sun Jul 27 14:03:42 2003 bw15.log:Script started on Sun Aug 10 10:53:46 2003 bw15.log:Script done on Sun Aug 10 12:53:04 2003 build options from make.conf: CFLAGS=-pipe -O WITH_LIBMAP=YES NOPROFILE=yes Non-commented kernel config options: machine sparc64 cpu SUN4U ident U60 maxusers 0 options OFW_NEWPCI options SCHED_4BSD #4BSD scheduler options INET #InterNETworking options FFS #Berkeley Fast Filesystem options SOFTUPDATES #Enable FFS soft updates support options UFS_ACL #Support for access control lists options UFS_DIRHASH #Improve performance on big directories options NFSCLIENT #Network Filesystem Client options NFSSERVER #Network Filesystem Server options CD9660 #ISO 9660 Filesystem options PROCFS #Process filesystem (requires PSEUDOFS) options PSEUDOFS #Pseudo-filesystem framework options COMPAT_43 #Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 #Keep this for a while options SCSI_DELAY=3000 #Delay (in ms) before probing SCSI options KTRACE #ktrace(1) syscall trace support options SYSVSHM #SYSV-style shared memory options SYSVMSG #SYSV-style message queues options SYSVSEM #SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING #Posix P1003_1B real-time extensions options SMP # Symmetric MultiProcessor Kernel device apb # Sun APB PCI-PCI bridge device ebus device isa device pci device sbus device ata device atadisk # ATA disk drives device atapicd # ATAPI CDROM drives device ahc # AHA2940 and onboard AIC7xxx devices device isp # Qlogic family device ispfw # Firmware module for Qlogic host adapters device sym # NCR/Symbios Logic (newer chipsets + those of `ncr') device scbus # SCSI bus (required) device ch # SCSI media changers device da # Direct Access (disks) device sa # Sequential Access (tape etc) device cd # CD device pass # Passthrough device (direct SCSI access) device ses # SCSI Environmental Services (and SAF-TE) device ofw_console # OpenBoot firmware console device device genclock # Generic clock interface device eeprom # eeprom (really an ebus driver for the MK48Txx) device "mk48txx" # Mostek MK48T02, MK48T08, MK48T59 clock device sab # Siemens SAB82532 based serial ports device miibus # MII bus support device gem # Sun GEM/Sun ERI/Apple GMAC device hme # Sun HME (Happy Meal Ethernet) device rl # RealTek 8129/8139 device random # Entropy device device loop # Network loopback device ether # Ethernet support device pty # Pseudo-ttys (telnet etc) device bpf #Berkeley packet filter options OFW_PCI_DEBUG Hardware: real memory = 805306368 (768 MB) cpu0: Sun Microsystems UltraSparc-II Processor (360.03 MHz CPU) cpu1: Sun Microsystems UltraSparc-II Processor (360.03 MHz CPU) da0: Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 16, 16bit), Tagged Queueing Enabled da0: 34732MB (71132960 512 byte sectors: 255H 63S/T 4427C)
