Certain views are unusually slow to load

[ebugden]

Slowness varies between user (ex. 40 s for @MatthewKhouzam, slightly longer for @arfio). @tahini suspects this is unusual and worth more exploration. Views to look into:

• Irq Analysis – latency vs time
• Futex contention analysis- latency vs time
• System call latency – latency vs time
• Flame chart

This is not urgent right now. @thefinaljob is working on #284 which will make this less confusing.

More context in #296 (comment)

It depends a lot on the trace being analyzed. In my case, it was pretty slow but the trace was >1GB. There should be some way of having a progress bar at least.

Good point! I added that this was not urgent and that @thefinaljob is working on adding a progress bar #284.

I created the issue to have a record, but we can close it if eventually we realize it was just the file size.

All of the latency vs. time views are currently filtered out client-side (#508) since these views contain discrete data and scatter plots aren't supported yet #45
