DBCC PROCCACHE Question.

What exactly does this command show you. I need to know what the numbers it
shows actually mean. I have been having SERIOUS performance issues with my
SQL cluster and just by looking at the numbers from this command it looks
like my stored proc cache just grows and grows. I think...
Are high numbers from this command a bad thing or just normal?
Any help appreciated.
TIA

The Lancair CompanyIf your proccache keeps growing that basically means you are not reusing
your query plans properly. That in and of itself can be a major performance
issue but this is simply one aspect of what could be a host of issues. You

plan reuse.
dbcc cachestats -- will show you hit ratios
dbcc memorystatus -- will show you how memory is divided inside SQL Server
(for SQL Server controlled memory grants)

Gert,
I don't suppose you can point me to any help about those commands. I can't
seem to find them in the T-SQL help and I'm not really sure exactly what the
y
are telling me.

I will digg up some info on cachestats, not handy right now.
