Network Monitor quite high CPU usage

Post by greensnow » Wed Jun 27, 2018 8:01 am

Whenever I have the network monitor running the process uses 2-8% CPU (2013 MBP).

Seems rather high.
Any way to reduce?

4.1.1 nightly (5169)
macOS 10.13.5

Just upgraded to Version 4.1.1 (5171).
CPU consumption for the 'Little Snitch Network Monitor' process is now generally between 2-4%. So improvement has been made.
The Macbook 12 inch is not a powerhouse but a fine piece of hardware to work with. Every % of CPU counts so if possible to reduce further it would be great!

Downgraded to Little Snitch 3.8.2: CPU consumption of Little Snitch Network Monitor super low again, user happy again :)

We have identified the cause for this: A memory leak in the kernel extension. The kext had to check lots of leaked memory when looking for traffic statistics.

The issue is fixed in 4.1.2 and in the new 4.1.3 nightly build.

Thanks! For me the issue is fixed indeed with 4.1.3 (5176).
The 'Little Snitch Network Monitor' process is most of the time below 1% cpu

Solved for me also in 4.1.2! Great job! The daemon now idles at 0-1% CPU usage, down from 6-8%.
