max server memory - not working??

Hi,

I have a production server that has been having weird slowdowns. I suspect memory.

I have set the 'max server memory' setting to use 6 gig (of 10).

But when I check the memory usage in task manager I get -

Physical memory
total   10239
cached 629
available 879
free 285

using a total of 8.95 gig ! When I check it is the SQL server service using 7,045,508k

What the heck? I thought max server memory @ 6 gig meant SQL would only use 6 gig?
