- Return meta-labels for the discovered targets via promutils.Labels instead of map[string]string. This improves the speed of generating meta-labels for discovered targets by up to 5x. - Remove memory allocations in hot paths during ScrapeWork generation. The ScrapeWork contains scrape settings for a single discovered target. This improves the service discovery speed by up to 2x.
