Aliaksandr Valialkin 2bbf62b6f6 lib/leveledbytebufferpool: do not pool byte slices bigger than 2^18 bytes ... Previously byte slices up to 2^20 bytes (e.g. 1Mb) were cached because of a typo in the commit c14dafce43 . This could result in increased memory usage when vmagent scrapes many regular targets, which expose relatively small number of metrics (e.g. up to a few thousand per target) and a few large targets such as kube-state-metrics, which expose more than 10 thousand metrics. This is common case for Kubernetes monitoring. While at it, remove pools for very small byte slices, since they are rarely used during scraping.		2024-06-13 17:02:05 +02:00
