So, ich habe jetzt die Infos. Vorab muss ich noch korrigieren, dass es
kein Pentium mit 1,6GHz sondern ein Celeron mit 2,66Gz ist. Da hatte ich
die Boards verwechselt. Der Systemmonitor zeigt bei "E/A Warten" die >95%
an!

Kann eigentlich EXT4 zusammen mit SQLite das Problem sein? Mir fällt die hohe CPU-Last und die "markanten Kopfbewegungen" vor allem bei Firefox und bei Liferea auf. Beide nutzen SQLite.
