Re: UltraSPARC versus AMD - Slowaris

Richly deserved IMNSHO. my current employer was bilked for many many months
for a piece of crap E10K that barely outperforms a couple of AMD chips. But
at many, many times the price. We finally upgraded/migrated to AIX/g5 chips
and run what was run on 20 cpus on 2.

If Sun pulls out of its slow Icarus dive to near-certain death, it'll be
a miracle. ( And, I guess, that'd be "a good thing"; always nice to have a
miracle. )

Sun's stock was at $65.00 in late 2000 and has rocketed to $3.50. I think somebody else besides us noticed too.

Well, you overlook one thing there. SUN has always has a

Am i dreaming?,

Have your heard of slowlaris?

May be you mean hardware performance, combined with a great OS (BSD
or
Linux)

I had to "upgrade" many Sunfire 280 (running slowlaris [8|9]) to BSD

because

of poor DB performance, after the upgrade, all run flawlessly. I only
wish a had made this switch before Just my $0.02

A lot of the PC systems lack that kind of I/O thruput. Just
compare a simple P4 with ATAPI drives to the same P4

with 320 SCSI drives

- the speed difference, particularly using any *nix, is
surprisingly significant and easily visible with the bare eye.

We are talking about server or pc?, we run postgres on several HP
dl380

(5i

SCSI controller) with great performance

There is a reason why a lot of the financial/insurance

institutions (having a

lot of transactions in their DB applications) use either

IBM mainframes or

SUN E10k's :-)
Personally I think a weaker processor with top of the line

I/O will perform

better for DB apps than the fastest processor with crappy I/O.

i guess the "my $0.02" is in order here :-)

i totally agree with this
