Does JFFS2 compress data in flash?

When I check the available space in Flash

df

Filesystem                    1k-blocks        Used    Available    Use% 
   Mounted on
/dev/mtdblock1            32000                5772    26228            
18%        /

But when I erase a file that is 702k big I get:

df

Filesystem                    1k-blocks        Used    Available    Use% 
   Mounted on
/dev/mtdblock1            32000                5648    26352            
18%        /

Which means that 124k have been freed.
I think there is a compression algorythm involved...?

Thanks a lot
