Subject: fsync vs fdatasync on Linux
Date: Sun, 18 Feb 2001 18:22:59 +0600 [thread overview]
Message-ID: <01021818225902.00766@dyp.perchine.com> (raw)
Hello,
as fas as I can see from fdatasync man page, and from the latest kernel
sources (2.4.1ac3, fs/buffer.c), they are equivalent.
Using of fdatasync in database can gain significant gain on systems which
supports it (on HP it gains up to 25% with pg_bench on PostgreSQL 7.1b5).
Are there any plans to implement this correctly? And due to what problems it
was not implemented yet?

Sincerely Yours,
