is R5-3600X better than R7-9700X? a little confused.
I have an old server of ovh RISE-GAME-1, with CPU r5-3600x, it works well. and today migrated the web to the new server rise-s with CPU R7-9700X, same condition, same web.
after restart the mysql, cpu go 100% in few seconds, then back to10%, new server after restart the mysql, cpu go 100%, and can't low down.
really confused. anyone have any advice how to check it? want to figure out the problem.
both same condition, iis+mysql+php5.5. and web program, migrate from old to new server
Comments
anyone can give some advice? thanks
Yes, the only advice here is...
check logsas this is 99.95% software (and operator) problem.It's fairly important to use kernel 5.x, or better, kernel 6.x to get the most out of moden Ryzen/EPYC systems.
Try a kernel upgrade, if you're comfortable in doing so, and see if that helps the situation.
Probably a bug in your code, check mysql server on the query stats to figure out which query it is.
The 9700X is definitely better; it even supports AVX512
Based on the applications you run on your server, I believe you are also using an old system. That's probably why it's slow.
i checked the slow log, and found the query code, after update the code, yes it works.
but still a little confused. why the same code in R5-3600X can run better?
i'm using windows 2019 ,iis-7 system
You should do a benchmark before running anything. Some dedi are broken from the get go.
I did a benchmark once got the server, and everything seems ok
Does Windows Server 2019 even fully support the new Ryzen CPUs?
emm, not sure, how to check it?
