memory usage issues

the memory usage on our SQL 2000 server keeps creeping up to near 1.5 gig
out of 2.5 gigs. is this normal? is there a way to prevent this? should it
be controlled somehow?From BOL:
--snip
To acquire as much memory as possible without generating excess paging I/O,
each instance of SQL Server sets a target of acquiring memory until free
physical memory on the computer is in the range of 4 MB to 10 MB. This range
was chosen because testing has shown that Windows NT and Windows 2000 have
minimal memory swapping until the memory allocations equal the available
physical memory minus 4 MB. An instance of SQL Server that is processing a
heavy workload keeps the free physical memory at the lower end (4 MB) of the
range; an instance that is processing a light workload keeps the free memory
at the higher end of the range (10 MB).
--snip
This behavior is expected and is designed for maximum performance on a
dedicated SQL server.

unless there is < 5 ( between 5 and 10 ) MB of free memory... Why work to
reduce memory utilization if there is no need?
