It looks interesting but his server configuration is so much bigger then 
mine.

I don't have any of the configurations addressed by Brian:

Please backup the current file before making any changes. You should comment out "readahead" and "iocache". In the quickread section change the "option cache-timeout" to 10 and change the "max-file-size" to the size of the largest file of which you have many, rounded up to the nearest factor of 4.

Do you have any examples or ideas how I can tweak it more? should I add 
more options?

Kind regards,
