Current system is:
4 X Intel(R) Xeon(TM) CPU 2.80GHz (8 cores)
8 G RAM
1.1 TB of storage (SCSI RAID 10 array, direct attached)
Red Hat AS4, 32 bit
Oracle 10.2.0.3 (32 bit)
2.3 G SGA
Replacement system is:
2 X Intel(R) Xeon(R) CPU E5310 @[EMAIL PROTECTED]
1.60GHz (8 cores)
16 G RAM
1.6 TB of storage (SCSI RAID !0 array, direct attached)
Red Hat
Oracle 10.2.0.3 (64 bit)
12 G SGA
I've got the hardware budget left to bump up the memory on the new
system a bit if that'll help and I'm tempted to do it (hence this
thread).
One totally off topic question I do have though is, does anybody have
experience with the new 4 core line of intel chips? My operations guys
are procuring these now instead of the old dual core Xeons, but they
make me nervous since the new ones re****t lower bogomips than the old
ones. I'm aware that the "bogo" in bogomips stands for bogus, so I'm
totally wiling to be convinced the new chips are, in fact, faster, but
I'd love to hear any real world experience here.
