Details

Currently when using the performance.mark/measure APIs, we store events in Performance::mUserEntries, which is just a resizable array. However, we often want to look up entries by name in this array, which involves scanning through it and can get quite costly if the array gets large. We should investigate using a hash table or something more specialized to avoid slowdowns here.
