Does anyone else have any decent comparisons of more real-world apps (not just synthetic benchmarks) between differing 64bit archs, especially opteron vs Intel? I currently have an 3.0GHz Xeon (w/ em64t), a 3.6Ghz xeon (w/ em64t) and some dual opterons (244,248, maybe 250 too). Those are for reviewing.
First I want to compare MySQL benchmarks, using both 32 and 64 bits binaries and a mysql compiled from source with gcc 3.4.x. The benchmark will consist
of a copy of our database and running a script that does some real-life queries on it with different concurrency levels. Secondly i want to compare
webserver performance, apache 2.x w/ dynamic PHP scripts and tux for static
files, lets see which platform is the best webserver. Alternativly I want to time some comilations (how fast can they compile a vanilla kernel 10 times etc, useless but a nice comparison ;)).
Would love to see more application comparisons though.
If you have any more idea\'s of real-world benchmarks, please say so, and i\'ll try to get them tested too and post the results back to the list.
Ultimatly I want to put together a series of (public available) real-world benchmarks which I want to run on quite some platforms to get a nice overview of speed improvements.
¿How much Gigabytes has the database? I mean, that for a real test, the database must have many millions of rows. With a database with few megabytes, its\'nt a real test for 64 bits. __________________________________ Registrate desde http://servicios.arnet.com.ar/registracion/registracion.asp?origenid=9 y participá de todos los beneficios del Portal Arnet.

I disagree, if I wanted a database with millions of rows i would take our forum database (currently over 30G), but than i would be testing the I/O subsystem, not the processor/memory combination. The database im using fits in 4G ram, so after the first minutes of testing there should be almost no diskreads (im even thinking of putting the database files on a ramdisk to be sure the I/O subsystem wont influence the results. I'm going to monitor the diskstats closely to see that the hardisk wont influence the results.
If i wanted to test the IO system i would go and get myself a huge database and do random selects, that way you can be sure mysql is reading almost nonstop from the disk. I do have such a benchscript, and i'm considering running them too, but my scsi disks died on me (all three) and i dont have any disks till monday. -kees
