Ivan Kelly updated BOOKKEEPER-235:
----------------------------------
Attachment: BOOKKEEPER-235.diff
New patch removes syncing completely, as a) this is only called from SyncThread
and b) LedgerCacheImpl#flushLedger and EntryLogger#flush both have their own
synchronisation.
> Bad syncing in entrylogger degrades performance for many concurrent ledgers
