NP-View is a CPU and Memory intensive application. At times, NP-View may appear to slow down and the UI may become unresponsive.
The most common issue being insufficient sizing of the desktop or server. Please validate the proper sizing of your system by clicking the links to the left.
Additional causes are listed below:
- Low Disk Space - If the system runs out of available disk space, this will limit the ability of NP-View to process and store data. To resolve this issue, the user can perform a disk cleanup or add additional disk resources.
- Insufficient CPU - NP-View is a CPU intensive application, if the processing requested exceeds the available resources, the system usability will slow. In some cases, NP-View is put into a virtual environment where the allocated resources are not available on the hardware and the system slows. In some other cases, if connectors are running at the same time users are navigating the topology, the resources will be consumed by data processing and the system may appear slow.
- Insufficient RAM - NP-View is a Memory intensive application, if the NP-View database exceeds the size of the available memory, the system usability may appear slow. NP-View utilizes a NoSQL in-memory database for performance. However, because the database is loaded into memory, if there is insufficient RAM on the system the database will become degraded or not run at all
- End user available memory - If the end user has an older PC with 8 gig of ram or less, the system may appear slow running on that PC.
- Excessive browser tabs - If the user has a large number of browser tabs open which consume a lot of memory, the system may appear slow on that PC.
- Large configuration files - If multiple configuration files are loaded into a workspace or view and each config has thousand rules, objects or endpoints, the rendering and moving of topology objects may appear to slow.
- Saving large views - Large views with a high number of endpoints may take a long time to save.
Please report any performance issues to technical support so they can be investigated.
