Questions about the rendering performance of Jetson NANO

Hi,
If you run multiple NvEglRenderer in single porocess, you will hit this issue:

Multiple instances of NvEglRenderer

Hello I am using Jetson TX2 for h264 video decoding and rendering with Tegra API JetPack 4.3 Ubuntu 18.04 and I have a question about right using of NvEglRenderer. I need to render 3 NvBuffer into 3 different X windows in 1 process. So I create 3 separate threads for rendering. I create NvEglRenderer with createEglRenderer() function inside each thread and set fps to 25. But it gives me something about 20 fps. I try to reproduce this on 00_video_decode sample. When I run 3 separate processes …

Would suggest run single NvEglrenderer in each process.
