Subject: EPRD and TIER vs bcache
Date: Fri, 13 Jul 2012 21:44:51 +0200 [thread overview]
Message-ID: <50007AB3.3080309@shiftmail.org> (raw)
Hello all dm developers
have you seen latest kernel projects by Mark Ruijter at www.lessfs.com?
he has an write-only caching block device with barrier correctness
(EPRD) and one tiered storage implementation (TIER, which also uses eprd
inside afaiu). I have not tested this stuff personally but seems very
interesting.
In particular, latest published benchmarks of TIER against BCACHE at
lessfs.com show TIER winning by a significant margin (about 2x). This
stroke me because I read that bcache might be introduced into the kernel
soon. Might TIER be a better choice?
Regards
S.
