Locust: percentiles in /stats/requests?

Created on 12 Aug 2015 · 3Comments · Source: locustio/locust

Do you think it would be a good idea to include percentiles in /stats/requests? There is some argument that average/median response times can be misleading and percentiles (eg. 50, 75, 95, 99) are a more accurate representation of performance?

median is a percentile (50th)... but I agree percentiles are _much_ more telling than an average.

@cgoldberg

median is a percentile (50th)

Thanks for the correction
