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
Roland,
which platform are you running these bits on ? Solaris or Linux ?
