Hi,

I am sorry I cannot give you precise answer but I was not doing any serious benchmarks. I do not have any numbers but some time ago I did some experiments and it looked like Opterons were faster. Comparision was done on indexing speed rather than searching and as far as I remember they have different disk controllers (SATA/SCSI) so it is not very meaningful test.
On stability - at the beginning I was really afraid about stability of Opteron box - it failed regulary - but after finding out it was a hardware problem (memory) - everything works without problems.


Regards,
Piotr

I run on Opterons as well for my search nodes and they are much quicker

enabled.

The opteron has a fast FSB, large cache and on a recent linux kernel the
stability is second to none.  Update 2 of the jre 1.5 also improved my
stability.

Hi Piotr,

Do you have any search speed performance comparison data between the
64-bit JVM on an Opteron versus an Intel xeon with the 32-bit JVM? I'd appreciate any info you have. Thanks,


Chris


Search engine runs on Opteron boxes with Linux and JVM 1.5 (64-bit
version). Web search engine is based on nutch code with some
