Re: Re: "--tuning" compile and runtime option (?) - Mailing list pgsql-hackers

    Indeed, as an avid user (and tuner, I suppose) of PostgreSQL, I can't
see how any configure option would be faster or better than the existing
command line /config file parameters -- it would only serve to make things
harder to deal with IMHO. "Tuning" PostgreSQL is pretty simple, and is
explained pretty well throughout the manual (especially in the section
titled "Understanding Performance"). We have -S -B and the fsync options,
<Austin Powers Voice> That's about it.. </Austin Powers Voice> --- right?
All are explained in the manual and are as easy to use as anyone could
ask...  Any OS tuning should be left up to the administrator as that's what
administrators are for :-)
   Just my humble $0.02 worth..
