Hi Simon,
it's too early yet to speak about MySQL scalability... :-)
it's only since few months there is *no more* regression on MySQL
performance while moving from 8 to 16 cores. But looking how quickly
it's progressing now things may change very quickly :-)
For the moment on my tests it gives:
- on 8 cores: 14.000 TPS
- on 16 cores: 17.500 TPS
- on 32 cores: 15.000 TPS (regression)
Rgds,
-Dimitri
