Original Pull Request: https://github.com/claunia/plist-cil/pull/45

State: closed
Merged: Yes

This PR improves the performance of the BinaryPropertyListWriter by using a Dictionary<NSObject, int> to store the indices of binary objects instead of a Collection<NSObject>. It removes the need to do an IndexOf, which scans the entire list. That is a very expensive O(N) operation.

This results in a 97% performance improvement on Windows (i.e. 30 times as fast) and a 98% performance improvement on Linux.
