NvBufferComposite, It takes too much time

i use ‘NvBufferComposite’ to composite two YUV buffer(2448x2048 + 320x240) on jetson nano and xavier nx (highest performance mode, about 1.4G HZ)
it takes about 8 ms.
And if i increase the resolution or buffer numer to composite, it takes more milliseconds.
This is too long, Is there any way to speed up.

Please set hardware VIC engine to max clock and try again:

Ok, this is effective and helpful. Thanks,DaneLLL.
