I asked similar question in DeepStream Libraries/Other Libraries/ https://devtalk.nvidia.com/default/topic/1044465/other-libraries/deepstream-3-0-on-tesla-p4-performance-issue/post/5299095/#5299095
I am using Tesla P4, TensorRT 5.*, DeepStream 3.0
I am running sample app with command
deepstream-app -c configs/deepstream-app/source30_720p_dec_infer-resnet_tiled_display_int8.txt
Initially it runs faster but with passage of time it slow down. I can see nvidia-smi, Volatile GPU-Util increases to 100% and temperature raised frequently to 90C and above.
In configurations I have [sink0] with type=2, sync=1
I can see following message on console
There may be a timestamping problem, or this computer is too slow. WARNING from sink_sub_bin_sink1: A lot of buffers are being dropped. Debug info: gstbasesink.c(2854): gst_base_sink_is_too_late (): /GstPipeline:pipeline/GstBin:processing_bin_0/GstBin:sink_bin/GstBin:sink_sub_bin1/GstEglGlesSink:sink_sub_bin_sink1:
Finally system hangs on and I can’t perform any action.
I tried another sample (tracker) screenshots are attached with 4 streams. Within less than 1 minute GPU-Util and temperature raised and warning appears.
