 Hi All,
 
 I have a general question.
 
 We have access to some new AMD64 based Dell Servers with 2 Core Duo 
 Xeons.  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.

 The conscencus accross a few different threads on various mailing lists
 seems to be to try running FreeBSD/i386 instead, therefore assuming
 perhaps that there are some issues with threading/openldap/nss_ldap on

 So, given the above information, my question is this:

 Knowing FreeBSD i386 can be run on AMD64 hardware, is there any
 disadvantage other than the obvious 64-bit support? We're using dual AMD
 Opteron based machines with 2GB ECC registered memory, so memory
 capacity shouldn't be an issue running 32bit, but how about smp support?


 Also, if anyone might have another idea or option to go with towards
 fixing the openldap/freebsd issue, that'd be even better still - but to
 be honest I lack the skills, time, and hardware neccessary to accomplish
 this on my own. I'm hoping that something between 5.3-RELEASE and
 5.4-RELEASE can resolv the issue, or at least to isolate it to
 FreeBSD/OpenLDAP/Samba/nss_ldap/? as the cause.

 In short, i386 on AMD64 good, bad, why?

i386 is _exactly_ as good on amd64 as it is on i386.
Still amd64 is even better. If you can afford to lose

many things, and we'll try and help you debug your

Thanks, I did not realize that there was an RC1 out for 6.0 already. Any

I'll see what I can do to maybe get 6.0-RC1 running on a desktop in here

   Yes, but what what libs and programs you may install that are i386 
based as opposed to 64-bit. You can seriously 'screw' up your system by 
having several programs be unrunnable if you mix and match 32-bit stuff 
with 64-bit stuff too much. Also, note that if you're using 32-bit stuff 
you aren't fully utilizing your 64-bit hardware.

   And btw, it's Athlon.

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. AFAIK 
there is no such compatibility the other way around.

I think what I meant is that once the kernel puts the CPU into amd64 
mode, it
can't go back into regular x86 mode. 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.

Yes, current AMD64 CPUs are fairly lower power even without the

He said Pentium-M.  It's a completely different processor than the 
Pentium 4-M.  Designed for mobile computing, it is best described as 
combining the best features of the Pentium 3 (short(er) pipeline, etc.) 
and the Pentium 4 (better branch predictor, etc.) with high-end power 
saving features to form a third processor far superior to the previous two.

Here's a first look at the chip:

Some benchmarks where a 1.6GHz Pentium-M destroys a 2.2GHz Pentium 4-M:

http://www.tomshardware.com/mobile/20030205/centrino-14.html
Battery life in the 6+ hour range is common with Pentium-M laptops. 
Here's the first look results (note the Pentium 4-M had a battery with 
over 20% greater capacity!):

If you value battery life, go with the Pentium-M.  If you *most highly* 
value performance, the Athlon64 is probably the way to go.

So far my athlon 64 3200+ has been one of the coolest running processors I've
ever owned... although I've never used it in a laptop, my friend's p4 2.8 is
running a lot hotter...

Yes, current AMD64 CPUs are fairly lower power even without the
low-power models.  We're seeing 1U dual Opteron boxes running at less
then 100F under load.

RE: AMD64 vs i386 for FreeBSD

2004-06-27 Thread Remi
See that's I'm thinking, the raw performance is very attractive to me!! So
what's this about a p4 1.7 outperforming a 2.8? You got link to benchmarks?

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 :)
