I'm in the process of fixing some other problems, and notice that disabling 50 devices at once is quick, but enabling 50+ devices takes forever. Sometimes I hit the php maximum runtime. Hopefully this isn't necessary and it could be sped up or could be run in parallel or in the background.

If you want to disable all devices you can use the query below:
update host SET disabled = 'on';

The reason that it is not as quick is probably due to syncing with remote pollers to ensure that data is up to date when enabling them. Simply bypassing that process using the above query may lead to other issues I would suspect but @TheWitness will know better than me.

- Certain Device actions cause the removal of poller items from the remote data collector
- Bulk Enabling Devices takes forever

Need to check a few more cases before completely resolved.

- Device Re-index operations not returning to correct page location
- Bulk Enabling Devices takes forever
- Also adding a 'Repopulate Poller Cache' option due to the quick save option not forcing a re-populate of the poller cache.
- Repositioning the Verbose query directly above the Data Query section of device edit for convenience.

This should get it.  Changed the logging just a bit.  Figured out what was happening.
