I have an application that needs to constantly (every 50ms), call to an MVC action, and pickup/drop off data.

I am using Linq to SQL and MVC because of how simple they are to implement, and I know that they aren't perfect when it comes to performance, but it works relatively well, but the best speed I can get with my current approach is 200ms (without requests overlapping).

Each call to the site will create a new instance of the datacontext, query/insert it and return that data.

Is there a way to have the datacontext static, but submitchanges say every 5 seconds, so that i am pretty much hitting an in-memory version of the data?
