Recently, in a colleague's question: when iterating over a slice, it would be better to move the loop condition out of the loop for len than the Golang compiler's optimization results.
That
func G0(a []int) int { L := Len(a) for I := 0; I L; I++ { } return 1}
Whether it will be better than
func G1(a []int) int { for I := 0; I Len(a); I++ { } retu

Generally, the performance and timing problems of dns are caused by suspicious query results. In this case, no matter whether the dns is parsed or not, the consequences are the same.
What should we do for actual problems such as long response time, timeout errors, and invalid cache? After all, these types of query responses are still possible to pass. It only requires more time. In fact, in this case, the waste of bandwidth is the real key issue.

PerconaThreadPool performance benchmark test MySQL starts from 5.5.16. in the commercial MySQL version, Thread Pool is used as the plug-in to provide official function support. Later, MariaDB also implemented this function, and Percona also followed up. In the past few days, we have conducted a thread pool comparison test on Percona 5.6.16, trying to find a more suitable configuration parameter.
