Slow attachment.url's about carrierwave-dropbox HOT 10 OPEN

Hi, I am experiencing same issue, image taking too much time.
Can anyone tell me whether this gem directly uploads image on dropbox or server is involved in uploading image to dropbox?
Because a friend of mine told me that if your server is doing this part then its gonna crush when there are 5 or 6 requests simultaneously.

Hello @izelnakri,

Thanks for reporting! Sorry for the late reply, I will try to take a look soon!

there are actually more issues with this gem, just like its paperclip sibling. Some of the issues I've raised in the paperclip gem is relevant for this gem as well. Please take a look at it: janko/paperclip-dropbox#36.

I wish I could contribute to the gem since it seems like one of the worst gems I'm currently using so far, days of frustration over some wrong implementations or bad conventions. (No offense here, just objective opinion). However I'm not very good with metaprogramming in ruby yet. Thanks for your interest!

@izelnakri , @robin850 I have same issue right now. However I can't simply specify Dropbox URL as it changes each time I upload file, for example:

dl.dropboxusercontent.com/1/view/df106vuup1mzftx/Apps/[YOURAPP/[YOURFILE]
dl.dropboxusercontent.com/1/view/mxbs026yru67ln0/Apps/[YOURAPP/[YOURFILE]
dl.dropboxusercontent.com/1/view/2cc9lrqlglfxga3/Apps/[YOURAPP/[YOURFILE]

Here is the command line output with rendering times of one view and 2 linked pictures:

Now the same view, no images (I commented out the whole link):

I repeat, this happens notoriously and I am trying to investigate whats wrong with the routing urls of this gem.

I am having similar issues with this gem as for as performance is concerned. I don't see any optimizations which are done on this, are there any tweaks we can do to avoid this performance issue.

Hi there!

Sorry for the very late response! Actually I'm wondering whether the problem lies in this gem ; this seems to be a problem on the dropbox_sdk gem:

require 'benchmark'
require 'dropbox_sdk'

session = DropboxSession.new("app_key", "app_secret")
session.set_access_token("access_token", "acces_token_secret")
client = DropboxClient.new(session, "dropbox")

puts Benchmark.measure {
  client.media("/path/to/existing/image.png")["url"]
}

It takes a whole second to run on my computer:

  0.010000   0.000000   0.010000 (  1.055575)

I will further investigate, thanks for reporting guys! 👍

Just wanted to confirm that the issue lies with dropbox_sdk gem (as @robin850 mentioned). I have run benchmarks on every method down the call stack, and the only point where it significantly slows down (sometimes up to 2 seconds!) is main HTTP call inside Dropbox SDK
