Subject: How much RAM is too much ?
Date: Thu, 22 Jul 2010 13:45:16 -0700 (PDT)
Message-ID: <819397.8724.qm@web120007.mail.ne1.yahoo.com> (raw)

Cost aside, are there any technical factors to consider before increasing RAM 
(assuming the system can support it) ? Is there a sweet spot beyond which more 
RAM does not help Postgres or actually harms ?

If my database is only couple of hundred Gigs, can I not just have RAM that big 
and have read from buffer all the time ?

Thank you !
