Matlab went to sleep?

Sorry for the silly subject works. What I meant is, my matlab starts up slow (20 sec or so) before giving me command window.
And once in a while, it takes 3 sec or so to calculate something simple as 'hex2dec('abce');' Right after the result is produced, it responsive as long as I keep doing things in the command window.
But as long as I go away and come back after a couple of minutes, it was like matlab went to sleep, 3 secs or so is needed to wake up for the new job.

Does this sleep behaviour only affect Matlab? If so, does The Windows Task Manager (if on Windows) indicate activity during these three seconds?

Usually this has to do with the path/current folder/license file being on a network drive.

The license activation mode I used was online, so I don't know if a local license file is used or not. But it sounds silly, if Matlab has to contact remote license once in a while for this type of activation.
Thanks for your sharing.
