The
/syncendpoint will wait up until thetimeoutparameter for new events to respond with, and the Matrix SDK defaults to passing 30 seconds (DEFAULT_SYNC_TIMEOUTin the source), but if a user is in enough rooms with enough updates then they will do a continuous stream of syncs with likely small responses. This adds async_delay_msconfig option to allow users to configure how long after the last sync finished before retrying. This should allow users seeing constant network or disk I/O due to frequent syncing to introduce a delay.
