[SunHELP] Oracle performance replies

[David Strom]

In reply to Q below about the 280R vs. V240... note that the 280R 
processors have 8MB L2 cache vs. 1MB L2 cache for the UltraSparc IIIi 
processors in the V240...  other things being equal, the L2 cache 
increase should help the 280R be faster... Also, check the memory speed 
& compare... faster is better.  You'll need to look at how many PCI 
slots for SCSI/FC HBAs, too.  There's always the cost factor to figure 
in -- how much $$ is your budget?

We are compare the E280 and V240 as our ORACLE application server.  Based
on on SUN engineer told me the performance should NOT much difference.  i
would like listen to your opinion?

Thanks.

Also, someone asked about PERF numbers, which are important for 
Oracle... I'm pretty sure that Oracle doesn't make (any/much?) use of 
floating point, so it's only the INT numbers that matter.  IIRC, the 
SpecINT is for 1 CPU & the the Rates are multi-cpu.  So, it depends on 
if you're looking at a multi-CPU system or a single-CPU system.


Just my persononal opinions above.
