Hi Craig,

Thanks for your help.

I temporarily disabled AV (Microsoft Security Essentials) and switched file caching off on the local drive but there is no noticeable change in performance.

The file caching is an interesting lead though, there may be something similar running - that's definitely something to go on.

Thanks again for your advice.

Regards,

Ben
