Screen sharing performanace differences on MAC and WINDOWS

[sunny_chandel]

Hi All

I am having a big issue of screen share latency (working on WINDOWS) which is about to 20 - 30 sec sometime and 10 - 15 sec in general. I was thinking that It could be because of my network limits but when on the same time and in the same network I publish my screen share from MAC, miracle is happening, there is unexpected difference and there is no latency and if there, it is sometimes about 2-3 sec hardly. My maximum users are using WINDOWS and so that I am searching a solution for this latency problem. Please suggest a solution.

Thanks.

If there are some special settings for Windows to publish screen?

Had the same problem, Windows delayed as long as a minute, Mac was fine...LCCS team could not resolve it, so, I dropped LCCS screen sharing from my app.

There aren't any special settings in the application for Windows vs. OSX, and while we had reports of problems we weren't able to systematically reproduce the problem.

Some things to look would be network bandwidth usage, maybe network errors (are these problems happening on wired connections or wireless ? Same connection for both Windows and Mac ?) You could look at network settings but I wouldn't know what to suggest that you could change.

If you can reproduce the problem (and can see that a Mac on the same network doesn't show it) you could run something like Wireshark and check what's going on with the packets.

Again, there is nothing inherently different between Windows and Mac (apart from the way the screenshots are captured, that is OS dependenent).

Hi Raff,

We have tested it on following combinations on port 443 , sending and receiving.

1. Screen sharing on MAC machine on LAN (Result: Good speed of sharing)

2. Screen sharing on MAC machine on WiFi (Result: Good speed of sharing)

3 Screen sharing on Windows machine on LAN (Result: Too much Latency in receiving)

4 Screen sharing on Windows machine on WiFi (Result: Too much Latency in receiving)

Specially we have noted on windows that after some time , data from windows machine (Any windows machine) screensharing addin process stop sending any significant upstream data(used netlimiter to verify this) , so reciver receives almost nothing or very delayed screen updates.

I tried to figure out using Wireshark , but not sure that which packet to look for which can cause issues.I do not see any dropped packets atleast in packet scan.But packet sending speed decreases after some time on Windows machine.

We use same settings of performance ,Quality ,Fps and Keyframes on Windows and MAC while sharing screen.

What to look in for wireshark.

Your inputs will be very helpfull.
