Yes, it’s ms. and GPU frequency have impact on the components performance, like nvinfer, nvstreammux, nvosd, nvtracker, nvvideoconvert, etc. some components used both CPU, GPU, you can find details from each plugin documentation.

Hi, Thanks for your response. deepstream-app (config file is: source12_1080p_dec_infer-resnet_tracker_tiled_display_fp16_tx2.txt ) has print messge like this, I want to know whether it is reasonable. Is compent latency unit is ms? Frame latency is about 700ms, but “PERF” is 25, how can they mat…

Did you run with local file? please be noted it’s only for rtsp stream or camera.

Yes, for deepstream-app it is local file. Do you mean the print messages “frame latency” and “component latency” in deepstream-app is useless?

No, the latency is only used for rtsp stream/camera. for local file, it will have large latency for decoder.

ok, thanks. The component latency is ms？ right？ Is it related to GPU frequency? Comp name = primary_gie in_system_timestamp = 1627981884921.563965 out_system_timestamp = 1627981884956.114990 component latency= 34.551025
