Re: [ADMIN] Benchmarking postgres on Solaris/Linux

What bus speeds?

533MHz on the 32-bit Intel will give you about 4.2Gbps of IO throughput...

I think the Sun will be 150MHz, 64bit is 2.4Gbps of IO. Correct me if i am wrong.

Thanks,
Anjan

We are looking into Sun V210 (2 x 1 GHz cpu, 2 gig ram, 5.8Os) vs. Dell 1750
(2 x 2.4 GHz xeon, 2 gig ram, RH3.0). database will mostly be
write intensive and disks will be on raid 10. Wondering if 64bit 1 GHz to
32bit 2.4 GHz make a big difference here.

Thanks!

One thing this very much depends on is what you're trying to do.
Suns have a reputation for greater reliability. While my own
experience with Sun hardware has been rather shy of sterling, I _can_
say that it stands head and shoulders above a lot of the x86 gear you
can get.

If you're planning to use Solaris on x86, don't bother. Solaris is a
slow, bloated pig compared to Linux, at least when it comes to
managing the largish number of processes that Postgres requires.

If pure speed is what you're after, I have found that 2-way, 32 bit
Linux on P-IIIs compares very favourably to 4 way 64 bit Ultra SPARC
IIs.
