How is MSSQL using memory?
http://www.sqlhacks.com/Administration/Memory-Usage
Memory is one the most important factor affecting MSSQL performance.
As an administrator, you should be monitoring the memory
regularly. When Microsoft SQL Server runs out of memory, it will use
virtual memory: ie: disk paging, which will grind MSSQL to a halt.
You can keep track of the memory with dbcc memorystatus
.

select语句前加：
declare @d datetime
set @d=getdate()
并在select语句后加：
select [语句执行花费时间(毫秒)]=datediff(ms,@d,getdate())
