Goal

I want to monitor the progress of the first time a fully synchornized realm is downloaded from the server. My realm file size is about 2MB and downloading it takes about 12 seconds on my old Google Nexus 5X.

Expected Results

Download progress should be updated frequently so I can show the progress to the user.

Actual Results

Download progress is zero the first 10 seconds, then a progress update a couple of times the last few seconds

Code Sample

val realm = Realm.getDefaultInstance()
syncUser.allSessions().forEach {
     it.addDownloadProgressListener(ProgressMode.CURRENT_CHANGES, progressListener)
}
doAsync {
    try {
        syncUser.allSessions().forEach {
            it.downloadAllServerChanges()
        }
    } finally {
        uiThread {
            realm.close()
        }
    }
}
