[FFmpeg-user] Why is my mp4 file larger when I do an encode with -threads 0

I did an encode of a set of pgm files with the following command
ffmpeg -r 1 -b -I frame_%05d.pgm -b 18000 -vcodec libx264 -vpre slow Arn.mp4
it generated an pm4 file of about 56K
But when I repeated the test and did
ffmpeg -r 1 -b -I frame_%05d.pgm -b 18000 - threads 0 -vcodec libx264 -vpre
it generated a file of about 102K bytes.
Can anyone tell me why the generated file is larger when using -threads 0?
