How to achieve an encoding frame rate of 2*4K@60 with nvmedia_6x/iep

Currently, I’ve implemented a video encoding program using the sample from linux-aarch64-orinx_6080.sdk/drive-linux/samples/nvmedia_6x/iep, which runs on the “DRIVE AGX Orin General”. When encoding two channels of 4K video into H.264, the frame rate can only reach around 25 FPS, with the NvMediaIEPBitsAvailable function taking approximately 43 ms per frame. Strangely, when encoding only one channel of 4K video, the per-frame time is about 21 ms. However, according to the official documentation, it should be capable of 3x 4K30 (H.265). I would like to ask how I should troubleshoot and improve my program?

Dear @liuhongfei ,
Could you check the discussion at Understanding NvENC parameters, benchmarks & bitrate results when using nvm_iep_sci if it helps ?
