Subject: compression ratio

Message-ID: <4DFF2F29.4040108@corp.mail.ru> (raw)
Hello all.
I`m new to btrfs and do some testing now.
What we have:
SL6 - kernel 2.6.32-131.2.1.el6.x86_64
mdadm RAID5 with 8 HDD - 27T partition.
Mount options is "noatime,noacl,compress-force"
I use scribe daemon to copy log files from 200 hosts to that partition
for stress testing.
But I found what compression ratio is really small.
Partition is full of regular log files - plain text. Most of them a big
ones(10-20Gb) and they grow in realtime.
du -hs /logs/
1.1T /logs/
And compressed size is(df -h):
908G
Regular gzip do a significant more ratio.
There is a problem here? File size? Realtime grow of a files?

Best regards,
