You mean 150MB - sorry then. That's definitely too much. Does this happen right after booting the system or at some point later on?
Can you post a screenshot of all your running processes in Task Manager please?

It's not terrible but it is a bit unusual. The most that any svchost.exe process on my system ever uses is about 40MB. Just about any installed non-Microsoft service could be responsible for this.

People need to stop poking their nose in Task Manager looking for a problem when there is no problem. This is not Windows XP, the Memory Manager does things differently.
