High CPU usage

High together

I'm using NetMaster on my Notebook with Windows 10. The Notebook is a state of the art machine with i9-Processor, 16 GB RAM, NVidia graphics and so on. NetMaster is just installed and should listen to my traffic. No blocking, speed limits etc is configured. But only the running NetMaster produces a high CPU traffic.

Attached some captures from the Task-Manager.

Why is this? What can I do to avoid this?

High CPU usage is possible, as even though NetMaster only listens to your traffic, it still has to process every network packet and classify it by application.

Having said that, it is our new product and there may still be room for performance optimisations. Do you know how much data NetMaster was handling during this CPU spike? In other words, how fast is your Internet connection?

Ok, some observations:

1. After rebooting the computer sometimes NetMaster shows high CPU usage.
2. If NetMaster shows high CPU usage only a reboot of the machine helps. It will not drop by itself.
3. If NetMaster works ok it stays ok. Therefore high CPU usage is there at all or not there at all.
4. My Intenet speed is > 400 MBit but most of the time only a few Bytes per second are used...
5. It seems, that the initialization of NetMaster most of the times works well but sometimes fails (high CPU)
6. Even when NetMaster shows high CPU the measured speed seems to be correct.
7. The computer where I observed this has many network connection (2 x Ethernet, WLan, Virtual Network, VPN...). Usually only 1 Ethernet is used to handle all transfers.

If you need more information please tell me. I like the product (except some flaws) and I'm looking forward what it becomes in the future. I own both, NetMaster and NetWorx but I do not like how NetWorks shows usage in the Task-Bar...

Thank you for sharing the additional observations.

The intermittent nature of this issue along with using a VPN service suggests there may be packet loops, where a third-party network driver and the NetMaster's driver keep forwarding a packet to each other causing above-normal CPU usage.

We have added a workaround in the latest build, please give it a go and let me know how it works for you.
