javascriptLimits: Space_Overhead Tuning for Low‑Traffic OCaml 5 Services
The goal is to lower the cloud bill for a native‑compiled OCaml service that receives only a handful of requests per hour. The primary knob is Gc.set ’s space_overhead parameter, which controls how aggressively the major GC runs: a higher value means fewer collections but a larger heap, while a lower value forces more frequent collections and a smaller heap.
ocamlWhat memory overhead does PromQL query evaluation impose on Prometheus instances?
Query Memory Overhead Calculation Prometheus query caching (queries.cache.enabled) is documented as a mechanism to reduce memory pressure during repeated query execution, yet the exact memory overhead calculation for PromQL query evaluation remains undocumented. This creates challenges for capacity planning when deploying complex queries that process high-ca
prometheusAssetManager Thread Pool Size: Memory Impact on Android
Goal: Determine how AssetManager.setThreadPoolSize influences peak memory consumption when loading large textures on Android devices. Constraints: Android's limited heap, varying device RAM, and the fact that AssetManager loads assets asynchronously in a thread pool. The API documentation does not describe the relationship between thread count and memory usa
libgdxWhat is the difference between “container_memory_working_set_bytes” and “container_memory_rss” metric on the container
I need to monitor my container memory usage running on kubernetes cluster. After read some articles there're two recommendations: container_memory_rss , container_memory_working_set_bytes The definitions of both metrics are said (from the cAdvisor code) container_memory_rss : The amount of anonymous and swap cache memory container_memory_working_set_bytes :
