"Count the number of active connections to a MySQL database. The MySQL command "show processlist" gives a list of all the active clients. However, by using the processlist table, in the information_schema database, we can sort and count the results within MySQL.

"This improves on #9892 by compressing the directory on the remote machine so that the amount of data transferred over the network is much smaller.

In other words, we are archiving and compressing a remote directory to our local box."
