Thanks for the reply Henrik, The settings: cache_mem 1 GB cache_dir ufs /cache/normal 60000 9600 256 I'm not sure about the cache_dir stuff, didn't know if it was better to have a lot of small dirs or a few large ones, I think I pulled this setting from someone setting up a cache about the same as mine in the archives. I think 60000 is 60000MB or 60GB?

Whats your cache_mem and cache_dir settings? Regards Henrik
