FFMpeg3 slow audio encoding

Description

Audio encoding from wav to aac is very slow in the ffmpeg3. Earlier it used to be fast in ffmpeg2. After upgrading to ffmpeg3 the encoding process is taking thrice the time.

Following is the command that I am using.

ffmpeg -i L.wav -i R.wav -i C.wav -i LFE.wav -i Ls.wav -i Rs.wav -filter_complex "[0:a][1:a][2:a][3:a][4:a][5:a] amerge=inputs=6[aout]" -map "[aout]" -b:a 640k -y test1.aac

Can you show the output of the exact same command with the old version that you say was fastest?

Output from new version.
