- [`max_over_time`](https://docs.victoriametrics.com/MetricsQL.html#max_over_time)
- [`min_over_time`](https://docs.victoriametrics.com/MetricsQL.html#min_over_time)
- [`rate`](https://docs.victoriametrics.com/MetricsQL.html#rate)
The optimization is enabled when these functions contain lookbehind window in square brackets bigger or equal to `6h` (the threshold can be changed via `-search.minWindowForInstantRollupOptimization` command-line flag). The optimization improves performance for SLO/SLI-like queries such as `avg_over_time(up[30d])` or `sum(rate(http_request_errors_total[3d])) / sum(rate(http_requests_total[3d]))`, which can be generated by [sloth](https://github.com/slok/sloth) or similar projects.
* FEATURE: `vmselect`: improve query performance on systems with big number of CPU cores (`>=32`). Add `-search.maxWorkersPerQuery` command-line flag, which can be used for fine-tuning query performance on systems with big number of CPU cores. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5195).
* FEATURE: `vmselect`: expose `vm_memory_intensive_queries_total` counter metric which gets increased each time `-search.logQueryMemoryUsage` memory limit is exceeded by a query. This metric should help to identify expensive and heavy queries without inspecting the logs.
