iCloud Drive Killing My Internet - nsurlsessiond

Every time I turned on my Macbook Retina that has a fresh installation of Yosemite and iCloud Drive my internet (Comcast) would screech to a halt. Here is a typical ping:

64 bytes from 64.233.181.104: icmp_seq=9 ttl=43 time=12185.025 ms

64 bytes from 64.233.181.104: icmp_seq=10 ttl=43 time=11140.532 ms

64 bytes from 64.233.181.104: icmp_seq=11 ttl=43 time=14193.938 ms

Request timeout for icmp_seq 19

Request timeout for icmp_seq 20

Request timeout for icmp_seq 21

Request timeout for icmp_seq 22

Request timeout for icmp_seq 23

Request timeout for icmp_seq 24

64 bytes from 64.233.181.104: icmp_seq=12 ttl=43 time=13060.219 ms

64 bytes from 64.233.181.104: icmp_seq=13 ttl=43 time=12063.440 ms

On and off and on and off like that while the Yosemite computer was on the network.

As soon as I turn off the Yosemite computer, the internet would be fine.

I suspected the culprit was iCloud Drive and when I turned on the Yosemite computer again I discovered the process “nsurlsessiond” sending out data constantly. And as expected, the internet became unusable with timeouts and response times like the above.

As soon as I disconected the Yosemite computer, all was well.

I’ve never had this happen with Dropbox uploads or Backblaze uploads.

OS X Yosemite (10.10)

I ran some tests comparing iCloud Drive to Dropbox to see how fast each uploaded a file and to see how it effected my internet. This is what I found:

I closed all apps to have a minimal effect on the network. I uploaded the file to each service separately. The file was the same 211.3 MB file.

iCloud Drive: 2 minutes 32 seconds

ping statistics ---

154 packets transmitted, 148 packets received, 3.9% packet loss

round-trip min/avg/max/stddev = 34.619/7593.152/20905.769/6540.356 ms

Dropbox: 2 minutes 51 seconds

ping statistics ---

181 packets transmitted, 180 packets received, 0.6% packet loss

round-trip min/avg/max/stddev = 35.381/212.434/3718.613/412.643 ms

So, iCloud drive was faster, however if you look at the ping statistics, the network is much worse off when iCloud drive is uploading a file. Much more packet loss and significantly worse response times.

Same here. I´m signing off the service until they offer the option to pause the sync with Cloud Drive as Dropbox does. It just ridiculous. All my internet speed goes to the service and I barely can surf or watch any video content. *****.

I have the same problem.

The funny thing is, I have only a few text files on iDrive.

Would hardly be the reason for a multi gigabyte ⚠ download.

nsurlsessiond is not only iCloud Drive. If you block it with Little Snitch , you won't be able to browse some websites or submit any forms. I ended up to block the ausyd-edge.icloud-content.com (17.248.155.9) only which is the only one responsible for the massive data usage. I'm on 10.10.1, have never had a problem like that before. I have no photos on cloud drive, only text files, there is no reason for it to download whatever it is downloading continuously.
