Using Google Backup&Sync

Backup&Sync Direct connection:
From  Win10 to Google: ~25MBps on 3 streams.

Backup&Sync via Chrome browser (UDP based):
From  Win10 to Google.com/drive: ~290Mbit on 3 streams

Numerous other tests performed to eliminate W10 issue vs Linux issues vs 
upload vs download.

Just wondering whether we have an esoteric issue with LACP between Cisco 
and Juniper gear.
