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
