LL boots up sluggish, becomes 'snappy' on logoff/logon

[Cedarviola]

Thanks Jerry, was not sure where this post belonged.

But think I've found a likely suspect, and it's wireless. After a powerup boot, if I toggle the wireless connection off and on, all is well. Same results as logging off/on.

If I disable wireless and power off/on. All is OK until I re-enable wireless. Then it becomes sluggy right away. If I then toggle wireless off/on all is well. All subsequent toggles are equally OK. It's the first toggle that does it.

Here is a step by step process to discovery. These were raw notes I was taking during the process  and may not make much sense.

Fresh install with no updates -- no problem
Performed updates and on completion idle CPU usage around 50% before reboot. This with wireless connection. And it seemed sluggish.
Press reboot button -- OK and TaskManager shows single digit usage.
Power down / power up -- Sluggy -- TaskManager shows ~ 50% CPU usage -- mind you, nothing else is running but 'Welcome to Linux Lite' -- I touched nothing.
Log off/on -- all's well -- TaskManager once again shows single digits.

Ahah! I disabled networking -- on power up all is well.
Enabled networking -- wireless still disabled -- All OK.
Re-enabled wireless -- NFG
Plugged in Cat5 instead of wireless -- All OK.
Unplugged Cat5 -- no wireless -- powerup boot All OK.
But connected WIFI -- NFG right away
Disabled WIFI -- All OK
Repeat -- same results

Now gonna try toggling WIFI -- Toggling WIFI after powerup boot has the same effect as logging off/on.
