applyBindingsWithValidation Running Slow

If I have a 100 items in my viewModelArray, the applyBindingsWithValidation() function takes between two and three seconds to run. (Includes jQuery time to find the trElement). Is there any way to speed this up? Or am I doing something wrong?

for (var i = 0; i < viewModelArray.length; i++) {
var line = viewModelArray[i];
var trElement = $('tr[data-partnumber="' + line.mouserPartNumber + '"]')[1];
if (line.mouserPartNumber && trElement) {
ko.applyBindingsWithValidation(line, trElement);
}
}

Start by reproducing the reported 2–3 second runtime with 100 items and the provided loop. Profile the jQuery tr[data-partnumber] lookup separately from ko.applyBindingsWithValidation to identify the bottleneck. Done means the cause is established and a measurable performance improvement or confirmed usage issue is documented.
