#12543 closed bug (duplicate)

Large selector performance regression

Reported by: [email protected] Owned by:
Priority: undecided Milestone: None
Component: unfiled Version: 1.8.1

I have a CRUD app (aka html with large tables) that was hit pretty hard with this. We updated to 1.8.1 and suddenly there were 4 second delays when users click a checkbox before it would be checked.

I managed to reduce the test case pretty significantly on jsbin:


The problem came down to, more or less, this:

               "tr[link] td:not(:has(a,input)), td[link]",
               function() { /* ... */});

It's not great code, but the 100x slow down is worse.

Meta-bug/feature request: setting degradation and regression as search term synonyms would have saved me the day I spent reducing my test.

Sorry...it's always hard to pick out the right terms in a search. It would be easier if there wasn't so much noise from people filing things that weren't bugs. Unfortunately that makes things that *are* bugs like yours harder to find.
