Test Amazon S3 downloads?
« on: March 14, 2012, 11:59:56 AM »

This is a call for some volunteers to help us decide whether to migrate our download videos from the existing server to Amazon's S3.

If you own Camera to Print & Screen 2011, could you please try downloading a file and post the speed of the download? C2PS is the only download currently on S3.

We have had mixed results so far (past 12 hours) with N.American downloads quite speedy but European/UK downloads slower than normal.

We'd love to get some Australia/N-Z & Asia feedback

Hi Chris,

I just tried downloading 2 of the Camera to Print and Screen (2011) files and was getting an average speed of about 3MB/sec. (ranged between 2.8 and 3.2 MB/sec.).
This compared to speeds last week for the LR4 tutorial of around 40-50 KB/sec.!

BTW, this is in N. America (Massachusetts).

Chris,

Downloading from Finland (EU) @ 73 KB/s. It is a bit faster than before but not exactly fast ;)

I would still prefer S3 if it would allow reliable multiple simultaneous downloads.

Hi Chris,

I downloaded C2PS02.zip ( from Germany) with a speed changing between 250kB/s and 800kB/s, which is in my opinion pretty good.

My internet-connection is capable of 1MB/s, so the peaks I could reach are very near the maximum speed available for me.

Best wishes

Robert

1.6 MB/sec which is much faster than last week LR4 downloads which were about 40 kB/sec.

Hi Chris,

I am not at home where I have a very high speed connection, but I am at a restrurant that I am involved  with but the speed is not that fast.
Was down loading one of the file that was 412MB it was going to take about 43 minutes to down load. But again this is not a real fast connection.
Will give it a try when I return home.

Best,

Stu

Downloaded C2ps-02 at 11:45MST 14:45EDT.
  Initial Maximum - 670KB/sec
  Later Minimum- 64KB/sec
  Later Maximum- 685KB/sec

  The above readings were taken in the order given; the first one was after the first quarter of the file. The last quarter of the file was relatively steady, averaging about 350KB/sec.

Australia here Chris.

Downloading for me at around 300 kb/s . About 10 times the speed of last week.

Cheers,
Alan.

Chris,
One additional data point which might be of interest. (Or not?)
Out of curiosity I just tried downloading one of the LR4 tutorial files for comparison, and it was getting up to 1.3MB/sec., or about 30 times faster than last week during crunch time.
So the S3 still appears to be ~2.5x faster even when your old server isn't stressed.

(In N. America, Massachusetts, at about 4:45 EDT.)

Yes, we know our server works well when there are less than 100 customers plugged in to the Store - it's the maxed out situation that remains to be seen...

Many thanks to all for their input. Please keep 'em coming.

450 KB/sec on Rogers Roger Hub which is quite fast for this time of day - suppertime. Certainly better than the 18 to 28 KB/sec download speed I had for most of the for the LR4 videos.

I just started 6 simultaneous downloads of files bigger than 200MB each (#1, 2, 5, 6, 7, and 9), and while all six were downloading, the download speeds ranged from 300KB/s to 960KB/s. Downloading the LR4 videos a week after they were released (once the feeding frenzy had subsided) I was getting speeds around 100KB/s, so I think this is much faster.

This is from Boston, MA. (7:00 pm on Wednesday, at a time when the main LuLa site seems slow to respond).

I downloaded a C2PS and then a LR4 at two different locations here are the numbers:

office
C2PS  ranged from 600kb to 980kb/s
LR4    ranged from 600lb to 1.2mb/s

home
C2PS  ranged from 1.9mb to 3.2mb/s avg 2.6-2.7mb/s
LR4    ranged from 1.6mb to 1.9mb/s

Hope this helps, late last week I was downloading around 200kb to 400kb/s at home

Ok! I think we will try putting the existing LR4 files on S3.

I'll post here when they are up

Kevin in Brisbane, Australia - getting 812 kB/sec from S3 (eg. c2ps-02.zip (282 MB) arrived in 6 minutes).

Also tried LR4_11 (264 MB) from your old-not-stressed server and was getting 265 kB/sec.
When I was downloading LR4 tutoral during stress time I was getting 15-20 kB/sec.

(My connection is ADSL2+ and a speed test on it says I get 6.5 Mbit/sec from a server in Australia)

Time - 7:00 pm Australian eastern standard time (UTC+10), which equates to 5:00 am in New York and 9:00 am in London.
Sorry about the late reply - I dared to stray from my computer today!  :)

Good job Chris!!!!

So the results are pretty good and we will proceed with the switch-over but....

The 'hacks' to our shopping cart have 'broken' a couple of other things in there on the Admin side. So we have to back out of Amazon for a few hours and try and fix those issues before continuing the migration. Stay tuned

Many thanks to everyone for your feedback. BTW there still seem to be some routing issues with Amazon S3 in Ireland. I'd love to hear from anyone in IE who can test the C2PS download...
