使用mongodump导出后,v3.x 相比 v2.6.6 mongorestore导入速度慢了不止一个数量级 大概200万的数据(2GB) 总共只需要5分钟的样子 v3.x不知道是不是因为使用了身份验证的原因导入只有3MB/S

I migrated and imported more than 300 GB of data. It took two days to import only a few hundred MB

I have also encountered situations where data recovery is slow or stuck. I was restoring data in a replica set environment. After checking the log, I found that: if the secondary node is disconnected, when executing the above recovery command on the primary node, due to the Arbiter The heartbeat mechanism will cause the following error:
2016-03-28T16:56:52.304+0800 I REPL [ReplicationExecutor] Error in heartbeat request to 192.168.8.37:27017; Location18915 Failed attempt to connect to 192.168.8.37:27017; couldn't connect to server 192.168.8.37:27017 (192.168.8.37), connection attempt failed
Then the entire progress bar got stuck.
