Aliaksandr Valialkin	5f2277624a	lib/{promscrape,leveledbytebufferpool}: rename getPoolIdAndCapacity to getPoolIDAndCapacity in order to make golint happy	2020-08-28 09:49:22 +03:00
Aliaksandr Valialkin	9a77ae9d1c	lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels ... Previously targets with big number of metrics and/or labels could generated too big buffers, which then could be re-used when scraping targets with small number of metrics. This resulted in memory waste. Now big buffers are used only for targets with big number of metrics / labels, while small buffers are used for targets with small number of metrics / labels.	2020-08-16 22:30:34 +03:00
Aliaksandr Valialkin	3ea6444219	lib/leveledbytebufferpool: allocate byte buffers with capacity rounded to the upper boundary for the given bucket ... This should reduce the number of resizings for the returned byte buffers.	2020-08-16 22:13:38 +03:00
Aliaksandr Valialkin	6e863376f7	lib/leveledbytebufferpool: pre-allocate byte slice with the given capacity if the pool is empty ... This should reduce memory allocations and copying when the byte slice is growing.	2020-08-15 01:41:59 +03:00
