Spike in HttpCache.EntryLockWait on Win dev channel starting around may 4th. Could this be related to Simple Cache trial? https://uma.googleplex.com/timeline_v2?q=%7B%22day_count%22%3A%2232%22%2C%22end_date%22%3A%222016%2F05%2F06%22%2C%22entries%22%3A%5B%7B%22bucket%22%3A%22%22%2C%22logScale%22%3Afalse%2C%22measure%22%3A%22percentile%22%2C%22percentile%22%3A%2250%22%2C%22showLowVolumeData%22%3Atrue%2C%22zeroBased%22%3Afalse%7D%5D%2C%22filters%22%3A%5B%7B%22fieldId%22%3A%22platform%22%2C%22operator%22%3A%22EQ%22%2C%22selected%22%3A%5B%5D%2C%22value%22%3A%22W%22%7D%2C%7B%22fieldId%22%3A%22channel%22%2C%22operator%22%3A%22EQ%22%2C%22selected%22%3A%5B%5D%2C%22value%22%3A%222%22%7D%2C%7B%22fieldId%22%3A%22milestone%22%2C%22operator%22%3A%22GE%22%2C%22selected%22%3A%5B%5D%2C%22value%22%3A%2248%22%7D%5D%2C%22histograms%22%3A%5B%22HttpCache.EntryLockWait%22%5D%2C%22window_size%22%3A3%7D
Don't think it is. There were no simple cache trial events around then; March 14th is the last big date for that. This bump seems in keeping with spikes we've seen previously. jkarlin@, any thoughts on what to do with this?
Nothing that I can think of. I agree that this looks in line with the occasional spikes we see: https://uma.googleplex.com/timeline_v2?q=%7B%22day_count%22%3A%22365%22%2C%22end_date%22%3A%222016%2F05%2F06%22%2C%22window_size%22%3A3%2C%22filters%22%3A%5B%7B%22fieldId%22%3A%22platform%22%2C%22operator%22%3A%22EQ%22%2C%22study%22%3A%22%22%2C%22selected%22%3A%5B%22W%22%5D%7D%2C%7B%22fieldId%22%3A%22channel%22%2C%22operator%22%3A%22EQ%22%2C%22study%22%3A%22%22%2C%22selected%22%3A%5B%222%22%5D%7D%5D%2C%22histograms%22%3A%5B%5B%22HttpCache.EntryLockWait%22%5D%5D%2C%22default_entry_values%22%3A%7B%22measureModel%22%3A%7B%22measure%22%3A%22%22%2C%22buckets%22%3A%5B%5D%2C%22percentiles%22%3A%5B%2250%22%5D%2C%22selectedFormulas%22%3A%5B%5D%2C%22allFormulas%22%3A%5B%5D%7D%2C%22zeroBased%22%3Atrue%2C%22logScale%22%3Afalse%2C%22showLowVolumeData%22%3Afalse%2C%22showVersionAnnotations%22%3Atrue%7D%2C%22entries%22%3A%5B%7B%22measureModel%22%3A%7B%22measure%22%3A%22percentile%22%7D%2C%22zeroBased%22%3Afalse%2C%22showLowVolumeData%22%3Atrue%7D%5D%7D
Gavin, can you watch this & close if things drop back down to normal? Let's follow up on this by 5/20.
The spike went down as previous ones did. Closing.
