Surviving a Production Launch with Node.js and MongoDB

Does anyone know what the difference in performance between a MongoDB that stores its entire data in memory, and a SQL Server (MSSQL, Oracle, Mysql, Postgres, etc) that stores its entire data in memory? Is the performance for MongoDB faster than the corresponding SQL server?

Yes, due to absence of SQL parsing and MVCC

Thanks. Would you know if it's a big difference, or just incrementally faster (~10%)?

It will depend on the type of workload. Some types will be faster, some will be slower. You'd have to run your own tests to see.
