Konkretno, moti me to:

root at backup1:~# dd if=/dev/zero bs=1M count=1024 | gzip | ssh root at backup2 "zcat > /dev/null"
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 18.4703 seconds, 58.1 MB/s

root at backup1:~# dd if=/dev/zero bs=1M count=1024 | ssh -C root at backup2 "cat > /dev/null"
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 890.529 seconds, 1.2 MB/s

S tem da je baje ssh -C uporablja isti zlib ... 

Očitno nekaj za na ustrezen openslowlaris bugtracker :)
