6119	"Web Spell Checker - ""finish checking"" takes ages to finish"	Wiktor Walc		"When having a larger document, the SpellChecker dialog becomes useless. I have tried editing the following document in CKEditor:

http://en.wikipedia.org/w/index.php?title=Black_hole&printable=yes

and after opening the ""SpellChecker"" dialog (with the ""Check Spelling"" button), after I clicked ""Finish Checking"" button inside of the dialog, it didn't close in a reasonable amount of time (it took almost 9 minutes, I have pretty fast internet connection). I have tested it in IE8.

To reproduce load the attached HTML source and use WSC.

I have no idea how spell checker works, but it looks like the problem is that the data is sent in a really small chunks, thus checking the whole document requires hundreds of HTTP requests.

There is one more thing that I do not understand here: I have  pressed the ""Check Spelling"" button, '''I did not change anything''' in the dialog and just pressed the ""Finish Checking"" button. Why is it taking so long if I did not change the document at all?

If it really has to take a lot of time, we could at least display an estimated time required to finish processing, because it is definitely not obvious that this operation may take so long."	Bug	confirmed	Normal		UI : Spell Checker			HasPatch, Review?	WebSpellChecker.net
