Stable Worldstones - Intel P4 vs AMD
Running -Stable make world with recent Intel and AMD hardware yielded some interesting results. One machine: CPU: AMD Athlon(tm) 64 Processor 3200+ (2010.31-MHz 686-class CPU) Origin = AuthenticAMD Id = 0x20ff0 Stepping = 0 Other machine: CPU: Intel(R) Pentium(R) 4 CPU 3.60GHz (3600.12-MHz 686-class CPU) Origin = GenuineIntel Id = 0xf34 Stepping = 4 The Intel machine had hyperthreading disabled in the bios. kernel config for both machines was GENERIC Running 'make world' several times on FreeBSD 6.0-STABLE from 11-26-05 a couple of representative timings were: AMD Athlon 64 45:42 45:19 Intel P4 55:22 54:57 Are there any optimizations for the P4 which might be added to the GENERIC kernel config to improve the performance ? -kim -- w8hdkim err gmail.com ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

BTW, my *personal* opinion is AMD implements much better pipelining and concurrent processing compared to the Intel platform. So what you see is not something entirely unexpected.

Specially look closely at the CFLAGS, COPTFLAGS and CPUTYPE variables. Also please be kind enough not to send in HTML mails in this list. It's really irritating to decipher mail content from within HTML tags for unlucky souls like me who use a text based mail client to read mails.
