hi,
i upgraded an Alfresco Commuity 3.4b to 4.0e, still with lucene index.
The machine is a Ubuntu 10.04 with Mysql database.
i have to import about 20000PDF documents (each aboul 200kb).
This should (and is currently) run via cifs.
in the last 3hours it imported about 20files.
I already defined background indexing:
but after importing the load of mysql grows up and stays at 199% CPU usage and aboud 2GB VirtMemory usage.
But i assume there must be some Mysql performancetuning i forgot. here are some parts from my.cnf.
hopefully somebody can point me to my error.
