libx264 conversion is very slow

Have anyone figured out how to optimize ffmpeg lib264 encoder. Here is a sample file:

Using this command, we get only 5-6 fs on quad code 2 mhz box running android.

String cmd = "-re -i /storage//sample.ts -c:v libx264 -c:a aac -b:v 704k -preset ultrafast -threads 16 -thread_type frame -strict experimental -hls_time 10 -hls_list_size 6 -hls_wrap 60 -start_number 1 -y " "storage/hls/index.m3u8";

Thank you.

It sounds like the -threads parameter is not affecting the performance
