I'm not really answering Andrew's question (I usually use WI once a year, in the fall) but my question is related so, hopefully, it can help answer Andrew's question as well.
I would like to hear from WI developers about reasons for WI to be slow at loading images in the "Identify" tab. With tens to hundreds of thousands of images, it is very important to minimize the time spent loading images as this loading time usually ends up taking longer than the actual photo identification.
If WI is slow at loading images, is that due to
- computer's hardware capacity
- browser's buffering capacity (is Firefox better than Chrome or others?)
- internet speed
- others
I'm sure it's a bit of all of the above but it would be good to know which are more important to optimize (e.g. one cannot necessarily change internet speed or buy a new computer but they can switch browsers, if that's the most limiting factor).
