See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1367). -* FEATURE: vmagent: show the number of samples the target returned during the last scrape on `/targets` and `/api/v1/targets` pages. This should simplify debugging targets, which may return too big or too low number of samples. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1377). * FEATURE: vmagent: change the default value for `-remoteWrite.queues` from 4 to `2 * numCPUs`. This should reduce scrape duration for highly loaded vmagent, which scrapes tens of thousands of targets. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1385). +* FEATURE: vmagent: show the number of samples the target returned during the last scrape on `/targets` and `/api/v1/targets` pages. This should simplify debugging targets, which may return too big or too low number of samples. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1377). * FEATURE: vmagent: show jobs with zero discovered targets on `/targets` page. This should help debugging improperly configured scrape configs. * BUGFIX: prevent from adding new samples to deleted time series after the rotation of the inverted index (the rotation is performed once per `-retentionPeriod`). See [this comment](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136) for details. +* BUGFIX: vmstorage: reduce disk write IO usage on systems with big number of CPU cores.
