Hallo,
ich habe diesen RaspberryPi also 700MHz mit 512MB.
Zu deinen Tipps:
Also 329424, was sagt mir diese Zahl denn?
hdparm hab ich wohl nicht:
Wieviele Prozesse/Threads mysqld laufen lässt weiß ich nicht, wie lese ich das aus?
Ich erwarte nicht viel, aber ich möchte schon das Mögliche, wenns geht, herausholen. Wenn es nicht geht, bin ich auch so zufrieden. :)
Gruß

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Enable the slow query log to troubleshoot bad queries
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
query_cache_limit (> 1M, or use smaller result sets)
Wieviele Prozesse/Threads mysqld laufen lässt weiß ich nicht, wie lese ich das aus?
