ich versuche mich mal so kurz wie möglich zu fassen. Ich habe einen Root Server XXL bei Hosteurope mit 48 GB Ram, 2 Cores (1 x AMD 12-Cores) und 4 × 1.000 GB im RAID 10.
Auf Plesk habe ich verzichtet und habe nach Anleitung ISPConfig installiert.
Auf dem Server läuft "nur" ein XTCommerce Shop mit einer SQL Datenbank. Die Datenbank ist rund 1 GB groß und hat immer eine hohe Auslastung. Nun bin ich eurer Anleitung aus diesem Thread gefolgt: http://www.rootforum.org/forum/viewtopi ... 03&t=36343
Es ist schon deutlich besser geworden, aber dennoch gibt es momente an denen Minutenlang nichts mehr geht, weil der Mysqlthread auf alles Cores voll ausgelastet ist.
Ich wäre euch unheimlich dankbar, wen ihr euch mal meine SQL Settings anschauen können und sagen würdet was ich evtl. falsch gemacht habe. Ich glaube, das ich zu viel verstellt habe ](*,)

So habe ich das Problem, das ich im htop den Prozess /usr/sbin/mysqld/ rund 30 mal habe, ohne das er Cpu nutzt. Nur 0.8 MEM%
Ich bin noch ein Anfänger im Servergebiet und danke vorab für eure Hilfe ;)
