poor performance on specific query
curl -s -X POST -d '{"jsonrpc": "2.0", "method": "account_history_api.enum_virtual_ops", "params": {"block_range_begin": 1838272, "block_range_end": 1838276, "group_by_block": true, "operation_begin": 2, "limit": 2, "filter": 16384}, "id": 1000}' $HAFAH
Where $HAFAH is address of newest hafah instance, on 5milion database it needs several seconds, on full database didn't finish when I'm writing this. Looks like there is problem with filter argument, maybe this might be related to #8 (closed)
