Can SQL Server WebAdmin degrade the performance of my site? Once upon a time a had to use the Parallels WebAdmin interface.

After contacting the support team that hosts my website and informing them that I must use the Webadmin, they informed me that:


  MS SQL WebAdmin can degrade the performance of your site, database and the overall server.


Is that true? How can a tool like that degrade performance? Should I try searching for a different web hosting provider?
Any application that runs queries against a SQL Server (or any database engine) instance will decrease the performance because it's extra load the server has to deal with. I assume the warning is just to cover themselves, legally.

What it comes down to is the scripts you run, and how much activity the application generates on its own. There may be options to disable the latter, which is usually a good idea when working against a production instance.

I'm not familiar with the particular product you mentioned (Azure?), so for example from Management Studio, I always disable IntelliSense by default on a production management box, because this runs queries behind the scenes to do its work. Activity Monitor is also a big consumer of resources, and sometimes people leave that tab open and forget about it.

So again, their warning is a standard thing; I would probably just ignore it.
