Thanks for your ticket.
This isn't strictly a bug as basically the browser is saying that "the page is taking a long time to load, do you want to wait for it to finish?". We have established a few bottlenecks when it comes to the loading of the Ark Media which can cause this message to appear, but have also release a number of versions that fix many of the performance issues that affected the Ark Media, therefore could you please check that you a running the latest version as this will have significant improvements.
Originally the Ark Media loaded all of the files that the user could access which was too much for users with large file directories, so the latest version only loads in a directory's files once that folder has been opened. It is then cached for later access. The only caveat we currently have with this system is that if your root media folder (for example images) has a large amount of folders & files in it then you will experience performance issues because the system will need to load each of these initially. Take the following 2 scenarios:
- You have your images folder. Inside this is 100 folders (all empty) and 100 files.
- You have your images folder. Inside this is just 10 folders (each with 100 folders & 100 files inside).
Now the 1st scenario has 200 items compared to the 2nd's 2000 directory items but the 1st scenario will experience a sluggish initial page load whereas the 2nd will have an extremely fast page load. If your media directory ressembles the 1st scenario then my suggestion to you is to consider organising/categorising your folders & files into sub directories. This will improve page load times significantly whilst also having the benefit of having a more organised media directory.
So to summarise; check your Ark Media version & analysis your media folders for potential improvements. Apart from that, we are aware of the above mentioned bottleneck and hope to have some further performance improvements in a later version of the Ark Media Manager.
