A bunch of the additional metrics stuff becomes problematic with thousands
of tasks. The striping stuff is significantly worse than the CSS striping (the
CSS striping loads quickly, where as the new JavaScript striping can take as
long as 30 seconds after the page loads). This is semi-easily fixable by only
doing the custom striping for the summary table. But, the page still takes a
while to *finish* loading (you can see it quickly, but it keeps doing JS for a
while) because (I think) of the Javascript to hide columns. It's possible this
could be fixed by using an ID rather than classname to find the columns to
hide, because the ID query selector is much more efficient. LMK how much of an
issue you think these are and I can file a JIRA appropriately.
