Wow, thanks for reporting this. I think I might have an idea where the bottleneck is, but I'll do some profiling and see what functions are taking the longest..

Hi, is there any progress on it? I have probably the same problem. We have some HTML which goes from email conversations, about 10k chars and browser freezes on stateFromHTML().

Confirmed. If trailing spaces removed, browser not freezes anymore, but performance is still bad. Parsing HTML from email conversation (about 10k chars) takes aprox. 420ms to parse. For comparison if I use covertFromHTML from draft-js itself, it is lightning fast (<50ms).

I totally know why this is happening. It's related to trimTrailingSpace (and the similar functions trimLeadingSpace and collapseWhiteSpace are just as bad). There's performance issues with manipulating the characterMetaData associated with the text.
I think this needs to be refactored so we trim all the text and then manipulate the meta data only once.
I'll try to get a fix out soon.
