@Holly0521 Are you able to measure the CPU load when the encoder is running (e.g. htop) and verify all cores are being fully utilized or not?
Can you share the yuv file you are encoding?
Hi @Holly0521 , I hope you are using the master, since there is a PR recently merged improves 10bit performance. https://github.com/OpenVisualCloud/SVT-HEVC/pull/460

Hi @intelmark ,The cpu utilization is 70%~80%. The file is very large and it's an normal 8k@10bit yuv file.

Hi @tianjunwork , the fps is 33.12 using the master and it cannot meet the real time requirement.
Hi @Holly0521 - Wondering if you able to try using without the -nb option in a real product deployment (-nb is used most for testing)? Also make sure AVX512 support is enabled for your system (comment the #define NON_AVX512_SUPPORT line in EbDefinitions.h and rebuild).
Is there an expectation of a target fps when encoding given the large frame size, bit depth, and Xeon server based on some other information you've seen?

Hi @intelmark ,I want to verify the actual execution speed of encoding one 8Kp60/10-bit streams. I have commented the #define NON_AVX512_SUPPORT line in EbDefinitions.h and rebuilt and the speed is the same as before. My server configuration is similar to Intel(R) Xeon(R) Platinum 8180, but the speed is much lower.
Hi @Holly0521 , I wonder where did you see the Xeon 8180 performance data you are comparing with?
Hi @Holly0521 , anything to discuss in this issue?
Hi @tianjunwork ,there's nothing to discuss. Thx a lot.
The average speed of encoding one 8Kp60/10-bit streams is 27.63. Need I to add some parameters or missing the operation process? Thanks a lot.
