beorn7 e22f26bc58 Move to a queue model for appending samples after all. ... Starting a goroutine takes 1-2µs on my laptop. From the "numbers every Go programmer should know", I had 300ns for a channel send in my mind. Turns out, on my laptop, it takes only 60ns. That's fast enough to warrant the machinery of yet another channel with a fixed set of worker goroutines feeding from it. The number chosen (8 for now) is low enough to not really afflict a measurable overhead (a big Prometheus server has >1000 goroutines running), but high enough to not make sample ingestion a bottleneck.		2015-02-13 14:26:54 +01:00
