Hi everyone, I try to set up an authentic bind server in the loopback address(127.0.0.1) in our recursive server of our testbed for test reason. When I send a large number of junk queries(5000QPS), the srrt of loopback server in cash is unexpectedly large. Does anyone know the reason? The srrt is normal when I dig or ping the loopback server by the way. Here is the dump_cache.db's content:
