any news on additional compression-schemes for zfs ? this is interesting research-topic, imho :)
so, some more real-world tests with zfs-fuse + lzo patch : -LZO------------------------------------------------ zfs set compression=lzo mypool time cp /vmware/vserver1/vserver1.vmdk /mypool real 7m8.540s user 0m0.708s sys 0m24.839s zfs get compressratio mypool NAME PROPERTY VALUE SOURCE mypool compressratio 1.74x - 1.7G vserver1.vmdk compressed 3.0G vserver1.vmdk uncompressed -LZJB------------------------------------------------ zfs set compression=lzjb mypool time cp /vmware/vserver1/vserver1.vmdk /mypool real 7m16.392s user 0m0.709s sys 0m25.107s zfs get compressratio mypool NAME PROPERTY VALUE SOURCE mypool compressratio 1.47x - 2.0G vserver1.vmdk compressed 3.0G vserver1.vmdk uncompressed -GZIP------------------------------------------------ zfs set compression=gzip mypool time cp /vmware/vserver1/vserver1.vmdk /mypool/ real 12m54.183s user 0m0.653s sys 0m24.933s zfs get compressratio NAME PROPERTY VALUE SOURCE mypool compressratio 2.02x - 1.5G vserver1.vmdk compressed 3.0G vserver1.vmdk uncompressed btw - lzo-patch for zfs-fuse (does apply to latest zfs-fuse sources) is at http://groups.google.com/group/zfs-fuse/attach/a489f630aa4aa189/zfs-lzo.diff.bz2?part=4 This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
