some other funny benchmark numbers:

i wondered how performance/compressratio of lzjb,lzo and gzip would compare if 
we have optimal compressible datastream.

since zfs handles repeating zero`s quite efficiently (i.e. allocating no space) 
i tried writing non-zero values.

the result is quite interesting, so i`m posting it here.

writing a 200meg file ( time dd if=/dev/zero bs=1024k count=200 |tr '\0' 'a' 
>test.dat ) has the following results (compression used |time needed 
|compressratio)

lzo   | 0m10.872s | 118.32x  <- (!)         
lzjb  | 0m11.886s | 27.94x         
gzip | 0m17.418s | 219.64x
