We are currently using i386 Dell Servers with a core duo processor. I recall from my MS Windows days that when there was the shift from 16-bit to 32-bit processors it did take a while for applications to support 32 bit. Sometimes 16-bit applications actually ran slower on the 32-bit hardware. I know this is a loaded question: - Will the AMD64 based FreeBSD 6.2 distribution with applications such as Postgresql, Apache, Python, Tomcat and SBCL be able to take advantage of the 64-bit quad processor? This is a very frequently asked question, so you might like to do a bit of research in the archives or on google.

Yes, if you compile them natively on AMD64. Whether this results in speedups depends on a lot of factors. Instruction words on AMD64 are longer than i386, so binaries tend to be bigger, but on the other hand you've got more general purpose registers. The general consensus seems to be that you _need_ AMD64 if you routinely run out of address space. In other situations it can be nice to have, but it depends on the apps and the workload. I've been using an AMD64 system as my main desktop machine for years without problems. There are some ports that won't work, but that's mostly x86 binaries like the flash plugin and nvidia drivers. Both of which I can well live without.

You only need to mix 32-bit and 64-bit software when you are running the AMD64 version. This is because some binaries are 32-bit only and some ports only work for 32-bit. The AMD64 version has optional compatibility with 32-bit i386 software.

It can run x86 binaries but it's not fully back in x86 mode, and I think some of the x86 instructions are gone in 64-bit mode, so it has to emulate them somehow. From what I understand 32-bit binaries run slightly slower when the cpu is in 64-bit mode because of this. From what I've read, you can't make a kernel go back into normal x86 mode until you reboot. You probably know about all this better than I do, it's been a long time since I read any tech specs for the cpu.

Which one would you guys recommend to run FreeBSD. Obviously the i386 would be easier to run, so I guess my question is what is the state of the AMD64 FreeBSD version? You do know you can run FreeBSD/i386 on the Athlon64 3200+ laptop, right? :-) A 3200+ running 32-bit FreeBSD will out-perform the P4 2.8GHz running the same OS. A Pentium-M 1.7Ghz will outperform a 2.8Ghz P4 too ;) If battery life is important to you I'd suggest not getting an AMD64. For raw performance it's pretty nice though :) - -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA3j2V5ZPcIHs/zowRAoZpAKCnZMb/Kxk9wElcBhktj9NPDPsPggCgh6b2 iasKpu5F998wHLaC5flWA+E= =QBEE -END PGP SIGNATURE- ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
