We have a WSUS server serving around 300 PC's and a couple of dozen servers and a discussion came up at work as to what products to include.
We have a single SQL 2005 instance on one of the servers and it has NEVER been updated. My first thought was to just tick the box for SQL 2005 and let WSUS do it's thing to upgrade to the latest service pack at least.
One of the other guys here has the opinion that having updates that are relevant to only a small selection of hosts would effect the performance of WSUS as a whole, claiming that each update does a 'check' against all the hosts or something similar. My argument is that manually updating these servers is obviously not working as the admins are not paying attention to what is needed.
So my question is:
Do updates that only effect a sub-set of the hosts effect the overall performance of the WSUS server in relation to ALL the hosts? (disk space is not an issue at this point)
Is there any performance justification for or against manually updating small amounts of products?
Basically I'm needing a rebuttal against his argument and I'm unable to find any concrete documentation to prove him wrong.
