Objet : impact of SPECTRE and MELTDOWN patches

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
