读取速度非常快，并且由于反向关系，数据在 50 毫秒内被查询。但是写事务非常非常慢。

对于像下面这样一个非常简单的写事务，它需要 > 20 秒才能完成。

realm.executeTransactionAsync { bgRealm ->
    val conversation = bgRealm.where(CollabcardAnswerRO::class.java)
        .equalTo("id", "123").findFirst()
    conversation?.answer = "Hello"
}

我使用日志检查了事务，发现写入事务块在 < 50 毫秒内执行，但提交事务或调用事务的 onSuccess 方法发生在 > 20 秒内。

另外，我发现一件有趣的事情是，如果我通过在协程 IO 调度程序中调用 executeTransaction 而不使用异步来执行相同的写入事务，它会将写入事务加速到 5-10 秒。但是5-10秒还是不好。

另外，我尝试删除任何通知侦听器，因为差异检查需要时间，但这并没有太大帮助。另外，我的写事务没有被其他事务阻止，我已经确认了这一点。
