large files take too long to load about simpylfold HOT 6 CLOSED

Thanks for the report.

Is there any chance you could provide a copy of the file in question (or a similar one that also takes a long time to load)? I don't have any Python files of that size, so it's difficult to analyze the performance of the folding algorithm on that scale.

It may be that the algorithm I'm using simply doesn't perform well past a certain buffer size. If that's the case, there may not be much that can be done about it without rethinking the entire approach. That said, if you can provide an example, I can at least take a look and see if there's any low-hanging fruit to be picked performance-wise.

After giving it a little more thought, there is one fairly obvious optimization I can try, that of memoizing the results of recursive calls to the s:NumContainingDefs function. I suspect that that could improve performance substantially on large buffers.

When I get a chance, I'll put together a patch. And again, if you can supply an example file, that would be quite helpful.

I sent a file to your email address.

I just pushed an optimization that improves performance when loading your example file by about 3-4 times on my machine. It's not instantaneous, but it's far more tolerable than it was. Let me know how it works for you.

Thanks. Will check it out.

Its bearable. Thanks for the patch.
