Subject:Re: MySQL runs on 16-cores server
View as plain text  
Hi,

   In what way can having more cores slow down MySQL (or any other app  
for that matter)? Are you simlpy referring to the fact that some  
mutlicore servers might be slower in single threaded preformance than  
a higher clocked single core system? If I have a mutlicore system with  
fast single threaded performance I wouldnt expect it to be slower in  
almost any cases with something like a mutliprocess database system,

thanks Andy.
