Call me stupid but I have done it again. So I did try to cover all the Chinesepod beginner and elementary lessons and add them to skritter. That is not advisable to do. Since there are hundreds of them and all of them do repeat the words from other lessons you do not add many new words but the number of lists totally crashes skritter. I am getting timeout errors when loading etc. It works perfectly without any problem in the IOS app but the site is now very much useless. I will have to nuke again and create one list of the words instead. So this is just a reminder to others using Chinesepod do not add all your lessons or you will experience severe delays. Guess I will have to add the intermediate lessons as one custom made list instead.

I have a custom, multi part list called "ChinesePod" with month sublists. Whatever lesson I study load up its Skritter list but then only select and add the new words to my personal ChinesePod list. Better from a technical perspective, easier to sort through as well, less repetition.

I am going in that direction too. Sort of just felt for testing the limitations in skritter for the past week:-)Already at around 100 lists you will experience speed degradation and around 700 lists you will have 500 errors most of the time you try to load the study page. I will machine parse the lists from my library now and create one Chinesepod lists for beginner and intermediate and another one for intermediate.

I have also added "too many" ChinesePod lists (and other lists too) and have to try many times before I can start studying. I think, however, that the conclusion from that should be different.

Adding the voacb lists of all ChinesePod lessons studied seems to me to be a reasonable thing to do. The skritter site should be able to cope with that. If the IOS app can, so can the normal site.

We will work on making it not crash now that we're aware of the problem, but speed issues may be solved by just not loading most of the less recently touched lessons in that case.

Nick:

Does the processing time depend only on the number of lists which were not finished yet, or on the total number of lists learned?

When skritter loads the study page does it need to go over all previously studied lists, even those that were finished, to see that no new words were added to them?

ChinesePod lists, and many other lists are "final", i.e., once defined they are not going to change. If the issue is checking that vocab lists did not changed, then introducing a category of "unchangable" lists may speed things up.

The issue is simply that we made certain pages gather info on all lists that you're studying, no matter how many of those there are. For the vast majority of people, that's not a strain on the system, but yeah if you study all those ChinesePod lists, that's going to start breaking things. I just have to build it so that it works more like the my words page, where it loads the first few, and only loads more if you want to see more. That will scale properly.
