The last issue of c't gave some 64bit benchmarks on Linux. They used IBMs DB2 for some midsize database benchmarking and the usual LAMP tests. I am still somewhat puzzled by the results! In a nutshell

* on DB2 benchmarks 64bit (OS and application) showed no performance gains on Nocona or Opteron. That i find most surprising - still not sure wether the DB2 demo version they got from IBM really is a 64bit app.

* LAMP showed hughe improvements when going to 64bit. Nevertheless it showed much more improvements when run on Opteron than on Nocona. Ratio was >2 : 1 under 64bit while Nocona was ahead of opteron under 32bit.

Cheers,
Jens
