Subject: [linux-lvm] howto speed-up thinpool-devices?
Date: Sat, 24 Aug 2013 10:42:37 +0200 [thread overview]
Message-ID: <521871FD.8000700@mglug.de> (raw)
Hi list,
Im using thinpool-devices (and snapshots, too). I know, thinpool-devices
arent the fastest one, but maybe there could make more use of read (and
maybe write) caching. In my test-system are 32GB of ram, but there is a
max use of cache about <1GB, not more, by heavily use of these devices.
Is it possible to speed up the reading with growing up the cache use?
The /sys/block/dm-X/.. directories have lots of parameters, but Im not
experienced for that. Maybe Im looking@the wrong place and modifying
kernel parameters (scheduler etc.) are the better way?
Tfh!
Oliver
