Avoiding value copying (issue 681212 and issue 682363) (renderer and browser side)
record idb value size

Clear browsing data action takes a long time ( issue 574819 )

Record txn total size from IDBValues and keys on commit for versionchange and regular separately (memory, time, record numbers)

Clear Index table's tombstones more proactively ( issue 704244 )
Record # of tombstones created in txn, cleared in txn
Could be causing "Very slow writes to IndexedDB database" (issue 692849)

Better scheduler for transactions and transaction tasks. (issue 693260)
?

Deleting object store is slow (issue 693799)
 - record time for deleting object store. If this is slow then we investigate.

Renderer process crash / large values (issue 500733)
Avoiding value copying (issue 681212 and issue 682363) (renderer and browser side)
 - record idb value size

Clear browsing data action takes a long time ( issue 574819 )
 - record time for storage partition clear browser data. Prioritize based on results.

Support large writing txns, esp for initialization from version change (issue 527995)
 - record the total idbvalue and key size, time, and operation count for txns, split on txn type (versionchange and normal)

Clear Index table's tombstones more proactively ( issue 704244 )
 - Record # of tombstones created and deleted in a txn. Based on possible imbalance, we prioritize clearing the on a timer or during readonly cursor sweeps.

Abort outstanding transactions under memory pressure (issue 612525)
 - Record # of running and pending transactions on memory pressure. Solution will depend on # of running and pending txns.
