One thing that is annoying though is that Combres seems to log everything it does. "

Use content from content's cache for Resource y" This is fine in development but unnecessary in production so I wanted to turn it off but couldn't find how to do this in any documentation.
The way I managed to turn off logging was to find the line in the web.config that combres put in that looks like this:
<combres definitionUrl="~/App_Data/combres.xml" logProvider="Combres.Loggers.Log4NetLogger" />
You simply need to remove the logProvider so it looks like this:
<combres definitionUrl="~/App_Data/combres.xml" />
If you still want logging on your development environment you can simply remove the logProvider attribute in a web.config transform.
