difffolded.pl doesn't appear to be working

[apodelko]

I am trying to get a diff flamegraph. While flamegraphs have significant difference, the diff graph shows only fraction of percent differences - which doesn't appear to be correct.

I call it as ./difffolded.pl oncpu_307_02_24_55_folded.out oncpu_308_16_01_13_folded.out | ./flamegrph.pl >308diff.svg

Attaching the source folded files and resulting flamegraph - which doesn't make sense to me. Am I missing something?

oncpu_307_02_24_55_folded.out.zip
oncpu_308_16_01_13_folded.out.zip

Thanks,
Alex
