Before repairing, it usually takes more than 60s to test once.
For example, here is the time consuming I tested:
1. Time-consuming: 77254 ms
2. Time-consuming: 77525 ms
3. Time-consuming: 77083 ms
4. Time-consuming: 76345 ms
5. Time-consuming: 76616 ms
I found 2 locations to be very time consuming.
1. Use socket to get host
`
org.junit.runners.model.TestTimedOutException: test timed out after 60000 milliseconds
at java.net.InetAddress.getLocalHost(InetAddress.java:1487)
at sun.management.VMManagementImpl.getVmId(VMManagementImpl.java:140)
`
2. The connection related to the host.
