这是个不错的优化。我下次更新 SVN 时加上。
更一般地，我们也可以考虑这个：
dbenv.set_lk_max_objects(10000);
dbenv.set_errfile(fopen(strErrorFile.c_str(), "a")); /// debug
dbenv.set_flags(DB_AUTO_COMMIT, 1);
+ dbenv.set_flags(DB_TXN_NOSYNC, 1);
ret = dbenv.open(strDataDir.c_str(),
DB_CREATE |
DB_INIT_LOCK |
DB_INIT_LOG |
那之后写钱包的刷盘就靠 CDB::Close() 里的 dbenv.txn_checkpoint(0, 0, 0) 了。

That's a good optimisation. I'll add that next time I update SVN.
More generally, we could also consider this:
dbenv.set_lk_max_objects(10000);
dbenv.set_errfile(fopen(strErrorFile.c_str(), "a")); /// debug
dbenv.set_flags(DB_AUTO_COMMIT, 1);
+ dbenv.set_flags(DB_TXN_NOSYNC, 1);
ret = dbenv.open(strDataDir.c_str(),
DB_CREATE |
DB_INIT_LOCK |
DB_INIT_LOG |
We would then rely on dbenv.txn_checkpoint(0, 0, 0) in CDB::Close() to flush after wallet writes.
