Hi

               I would like to know what are the recommendation to resolve the problem of performance impact after applying the SPECTRE and MELTDOWN patches ?

               Do we have to add more CPUs ?

 

               NB : I have tested on one of our production database and I get an impact of ~25%... Do you have such a result ?

 

               Thanks in advance.

 

Best Regards
