Condor Watch website slow #77

Closed vjbakker closed 10 years ago

vjbakker commented 10 years ago

I am getting several reports that the Condor Watch site is very slow. I have not experienced this myself. Here are a few of the reports.

"Hi Vickie, You may already know, but in case you don't...the experience on CW from the user end has gotten unbearably slow. Long delays between marking an object and waiting for the software to respond. It takes five minutes what used to take 2 minutes. Consequently, I can only do two or three classifications before frustration sets in. Milton"

I asked our moderator to see if she had experienced this, and she said yes "to the point I left because it was unusable. The cursor took 5 seconds to move after you moved your mouse and 5 seconds for the 'click' to take. I thought it was my browser and wrote him back to say I wondered if it was the site "since it was both of us? but hadn't heard back. No other area on Zoo did this so it had to be CW."

Then Milton again today: " Today was somewhat better; each image started out working smoothly, and then would get slower with each animal I marked. I keep my cache emptied all the time, to be sure that's not the cause. Scrolling to zoom in was affected most of all. Strangely, each image worked great the first few clicks, and then got slower and slower. I'm keeping track of the time of day too, to see if that has any effect...maybe due to increased traffic (local or at the Zoo). I'll give you a report in a week or so if things persist in this way. Things are working fine for me at several other Zoo sites with no delays"

I just tried the site and I concur that this is a real problem.

I wonder if it could be browser-specific. I have not experienced this issue on Firefox. Vickie

That's unsettling for sure. I did 5 quickly this morning and didn't experience anything. I'm using the latest Chrome on OSX.

If I could get additional details such as browsers, usage, etc, I'll look into troubleshooting this.

You're right Vickie, there are big differences between browsers. I used Safari 7.0.6 and it worked fine, but it is slow on Chrome (37.0--latest). My computer is OSX Maverick.

Our moderator also speculated it's Chrome and related to a new Chrome update that had a lot of problems. I put a solicitation on Talk for info from other users. V

I don't see a timing problem on Chrome Version 37.0.2062.124 or Chrome Canary Version 40.0.2175.0 canary (64-bit) (beta developer version of Chrome ). I only loaded a handful of subjects.

I noticed some resources don't load (not found- 404 errors) .

I now have a number of users commenting on a Talk page devoted to this. Could you please refer to this page for more details on user experiences. Since we don't have tons of users, it would be great to keep our regulars happy. Thanks!! http://talk.condorwatch.org/#/boards/BCW0000001/discussions/DCW00002se

Also, in a separate Talk msg, I got this from a user: "I did 30 classifications, and things just go slower the longer I was on each image. Take your typical 20+ raven image...by the end, it would take 5-6 seconds before I could move to the next raven. Scrolling to zoom in and out worked great (!) strangely....I say strangely, because that glitch has been with me and CW for a loooong time. In case Zoo asks, I had all my extensions turned off, which did not change the slow responses. Emptying my history and cache didn't change it either. Today, CW is working great in both Google Chrome, and Firefox. No glitches whatsoever with 7 classifications, so I'm going to keep classifying today while the going is good."

For at least one user on that thread the problem could be that the Zooniverse library doesn't work with Chormium on Linux by default.

Otherwise it seems like it might be a memory problem. @sturad experienced slowness marking a lot of objects on his machine, but I did not.
