how we can use mysql tunning on server or AA panel
aaP_technicalteamdev try to use fastcgi, I also experienced this before. after i use fastcgi everything is normal 
and if you want, you can use system hardening and anti-intrusion.
thanks for replying
Is it available FastCgi on AA Panel or need to download via command
Please explain
Even a big problem in AA Panel
