# Performance-related P4V properties

If a user connects to a new Perforce service, performance-related properties are reloaded for the Perforce service to which the user has most recently connected.

Property | P4V > Edit > Preferences | Default | Meaning | Since P4V Version
--- | --- | --- | --- | ---
P4V.Performance.DirFetchSize | Number of files per directory fetched at a time in the Depot tree | 0 | Number of files to fetch at any one time. `0`, the default, means fetch all files. If set to a non-zero value, the minimum is 500 and we recommend 1000. | 2020.2
`P4V.Performance.FetchCount` | Number of changelists, jobs... to fetch at a time | `100` | Number of changelists, jobs, branch mappings, or labels to fetch at any one time. `0` means fetch all changelists, jobs, branch mappings, or labels. | 2013.1
`P4V.Performance.OpenedLimit` | N/A | `1000` | Limits the number of files to check in the 'opened' call during an undo operation. If the number of files to undo exceeds the configured value, a popup informs the user that no opened check will be performed, and asks if the user wants to complete the operation. If set to `0`, even one file exceeds the configured value. | 2013.1

`P4V.Performance.ReconnectInterval` | Auto-reconnect P4V to the server | not set | If not set (default), P4V uses the local Preference setting. If set to `0`, the autoreconnect feature is disabled (overrides the local setting). If set to a positive integer, indicates the number of seconds to wait between attempts to reconnect P4V to the server (overrides the local setting). | 2022.1
`P4V.Performance.ReportGlobalLocks` | N/A | `On` | If `Off`, P4V does not report global locks on edge servers and does not add the `-L` and `-OL` options to the p4 fstat command. | 2021.4

Users can still single-select a stream in the graph and refresh the stream to run the `istat` command for that stream and get the copy/merge flow information. | 2013.4
