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,
