Description
Implement MXStore with https://realm.io.
A prototype has been done to test storing of rooms states, which makes a lot of IO accesses with MXFileStore.
With MXFileStore, the first write and every change in Matrix HQ state takes 2.4s on my 5s
With Realm, the first write of 13k state events takes 4.4s but next updates take few ms
Time to store Matrix HQ state | First write (ms) | Update of a single state event (ms)
-|-|-
MXFileStore | 2400 | 2400
Realm hack | 4400 | few
From the 1st update, Realm is the winner.
Loading seems similar in both cases.
Implementation has been started at https://github.com/matrix-org/matrix-ios-sdk/tree/MXRealmStore.

Research direction
Start by reviewing the MXRealmStore branch and comparing its prototype with MXFileStore. Trace how room states are stored and updated, then verify that the Realm implementation covers the required Matrix HQ state operations and preserves comparable loading behavior. The issue provides performance observations but no specific test or acceptance command.
