« Hide

Idea took nearly 10 minutes to reformat an 8600 line XML file. This is weird, considering that the depth of the document is 5 levels at the deepest point.

your snapshot has no traces of reformat but only brace highlighting stuff that you can switch off. Please, start getting snapshot before reformat and finish after.

I repeated the experiment and here are the results with and without highlighting (the second time the inspector has turned it's back on me)

I noticed that IDEA actually relay-outs the XML in less than 20 secs, but then it spends minutes matching braces (that's why I took 2 snapshots the second time).
