ko.validation.group performance hit

We have a view model with very few observables, and only 1 that has validation, it has a observableArray with ~90 items, it also as very few observables and one with validation so we have 90 + 1 that needs to be tracked by the validation framework.

ko.validation.group(this) takes 350 ms in firefox / chrome and in IE7 the script wont complete, it hangs and says that the script didnt respond

Looks like there are serious performance problems with ko.validation.group, i need it to disable save buttons and such

Thanks, Anders

Start at ko.validation.group and reproduce the reported case with a view model containing an observableArray of about 90 items and one validated observable. Compare execution in Firefox, Chrome, and IE7; done means the grouping completes without the reported hang and its performance is substantially improved.
