Re: [PERFORM] [ADMIN] Benchmarking postgres on Solaris/Linux

[Anjan Dave]

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.

        The fact that technology doesn't work is no bar to success in the
        marketplace.

        TIP 2: you can get off all lists at once with the unregister command
            (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
