Hi ops,

Has the swift capacity been increased yet thanks to the new hardware? If so, could we resume the discussion of "pre"generating specific thumbnail sizes at upload time?

Media Viewer could benefit greatly from this performance-wise. As seen on this graph, the launch to all wikis affected the average considerably, since users started hitting a lot of images that didn't have Media Viewer-sized thumbnails yet: http://multimedia-metrics.wmflabs.org/dashboards/mmv#overall_network_performance-graphs-tab

This looks pretty bad. Thanks for calling it out.

Thumbnailing improvements are still in the works on our end, and the idea of not using swift anymore for those is definitely on the team's radar (we've started working on more modest thumbnailing improvements at this point)

May I ask: what is the range of this radar? Radar signal declines in quality as distance increases, and it is vulnerable to interference from diverse factors, like atmospheric turbulence and birds.

Nobody likes sinking time, energy and hardware on an architecture that doesn't work. Even when it's the right thing to do. I think appetite for this work might grow if some there were some definite plans afoot for moving us past it, to a setup that works.
