Crosswalk heavy RAM usage?

Hey guys,
just want to ask you if you run already into memory problems with Meteor + Crosswalk? Just to give you an example:

Myapp - 124 MB (just after start)
Spotify - 64 MB
Chrone - 21 MB

We’ve developed a chat application and just subscribing to all opened chats and the last 20 messages. In my case I’ve opened about 10 chats on beginning.
