Every request rendering static files went from 0.5 sec to about 20 secs to render. \r\n\r\nWe tried to debug what led to this increase but could not find it.

Moving to the newer ManifestStaticFilesStorage replaces all the round-trips with a local filesystem read.\r\n\r\nMy bad. Thanks for following up folks."}}
