Hi, using your latest web SDK 1.7, we are getting very high CPU loads on our platforms. This was acceptable on our ‘stronger’ models, but is very bad on our ‘low-end’ model (nevertheless a 4x core Intel cpu i3-7100U CPU @ 2.40GHz), as video / audio begins stuttering and/or A/V is out of sync the zoom application is basically the only application running on the machine, occupying the CPU most of the time. if muting VIDEO from the local side (where we see the performnace problems / high cpu load), we receive audio / video in acceptable quality and delay (between audio/video) suspecting from the WASM section of your API description: preLoadWasm() and also by observing GPU load(which is not changing when starting up zoom JS), we suspect that you do all the en/decoding in JS? also: using the ‘normal’ browser based webapp in chromium 78 (i.e. the non-JS SDK client), the platform in question delivers sufficient audio/video quality and delay. Is there any possibility to improve this, by e.g. using different webassemblies, restricting resolution, …? are there plans to improve this performance issue in an upcoming JS SDK version? switch to chromium based en/decoding, instead of JS code? thx Hari

Hey everyone, We are working to fix this in the 1.9.0 Web SDK release. Stay updated here: [image] Web SDK - Upcoming Changes - Stay Up To Date - Documentation Web SDK Thanks, Tommy

Hi, this thread follows an issue I’m also having. We are using a custom built i7 7700k 4 core. 16 gb of ram. We are using the on-board graphics with no dedicated gpu. There are high cpu loads once we connect to audio or video, and both at the same time. The issue was repeatable, on a fresh install on windows 10, whichever the latest build is.

Hi @tommy , We are also facing the same CPU spike issue which is quickly draining the battery and produce more heat. CPU % was went up to 80%. We are accessing from India. We used the latest Web SDK 1.7.7 both CDN and Local. Google Chrome Version 81.0.4044.138 (Official Build) (64-bit) macOS Catalina Version 10.15.3 (19D76) MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) Processor 2.3 GHz Dual-Core Intel Core i5 Memory 8 GB 2133 MHz LPDDR3 Graphics Intel Iris Plus Graphics 640 1536 MB

Using the zoom client, I am also getting very high cpu usage. On a Lenovo T590 (4k resolution), viewing with full screen results in >100% cpu usage on ubuntu 20.04. Rescaling the window to a smaller size can get the cpu down to 30-50%.

same problem here… my mac doesn’t run anything else when in a zoom meeting

Hey @gborges, @s.tootle, @karthikeyan.ramaraj, @spongiephone, @pierre.a.lafortune, Thanks for reporting this. I will forward these details to our Web SDK engineers. (CS-1387) Thanks, Tommy

Any update on this issue? some of our users are experiencing similar high CPU usage with desktop clients. Dell Precision 3610MT 16GB RAM AMD Radeon Firepro W2100 Win10 Enterprise 64bit

Same here, my CPU is going through the roof (>100%) , leaving my MacBook Pro 2019 so hot that I can barely touch it.

Getting high CPU when initiating zoom & also when having meetings. Slows down the system & hangs intermittently. Running on Win 10

Not sure if this is relevant. I just came back to my laptop hours after finishing a zoom call (with screen sharing at some point) to find the fan running and zoom using 100% cpu. No meeting was running! In fact it wasn’t connected to the internet anymore. Ubuntu 18.04 4.15.0-101-generic kernel with zoom 5.0.413237.0524

I’m running a MacBook Pro 15-in 2018, 2.9 GHz, 6-Core intel i9 with 32GB of 2400 Mhz DDR4 Ram. I’m absolution maxing all processors when running zoom. Everything grinds to a halt, it effects audio, and video screen sharing etc. I’m I turn off every other program, except the one I’m sharing. Try to free up all resources, change the screen resolution to low, turn off video… just audio and screen. And it is almost non-useable.
