Hello,

The CPU usage is a very objective thing and can vary by many different factors. For me, for example on Core i5 4460, the CPU usage is 0%, while Zoiper5 is idling. But if you have a very weak processor, it might be slightly more. As overall, Zoiper is pretty lightweight.

I know it, but Core i7-4510U... In linux... 3-4% idle

Linphone - 0% idle, but sound - bad...

I'll provide this feedback to our QA team, so they can test a bit on Linux.

I see the same problem.  My machine has an Intel Core i7-7567U @ 3.5Gz x 4, running Pop-OS (really Ubuntu) 19.04, with Zoiper 5 installed about two weeks ago.  I'm seeing over 5% CPU from Zoiper during idle.  There are two zoiper processes, one using 4.7%, and the other 0.7%.  This is idle.  No call.  This is too much CPU!

There is something in Zoiper software that is looping much too quickly.  A status check, or GUI refresh, or something that should NOT be running without reasonable idle time of at least 500 milliseconds or several seconds per loop.  

Wasted electricity, wasted heat, and wasted time listening to my CPU fan cycle too often. Why should one idle app rob my computer of 5% power at all times?  Here's a copy of my 'top' output.  (Easier to read if you view with a monospaced font.)  Zoiper is at the top almost all the time.

I confirm:

between 6% and 10% cpu usage while idle...

Guys,

I want to let you know that we have indeed found that Zoiper is using slightly more CPU on Linux compared to the other operating systems. The issue is resolved, you should see improvement with our next update. : )
