Comments on: Is 64-bit DB2 Express-C better than 32-bit? http://freedb2.com/2008/06/05/is-64-bit-db2-express-c-better-than-32-bit/ Big Data, Hadoop, free databases and a whole lot of Cloud Computing Thu, 29 Mar 2012 17:31:30 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Leon http://freedb2.com/2008/06/05/is-64-bit-db2-express-c-better-than-32-bit/comment-page-1/#comment-8005 Leon Sun, 25 Apr 2010 22:56:03 +0000 http://freedb2.wordpress.com/?p=10#comment-8005 The was a very important part of the sentence before the one you quoted: "... if you are running 32-bit OS on a system with 4GB of memory,". The way both Linux 32-bit and Windows 32-bit allocate memory pretty much dictates that memory left for applications is going to be no more than 2.4-3.8GB. This has nothing to do with DB2 and everything to do with the operating system. That is why people look to 64-bit OS. What I was trying to say is that even if you only have 4GB of physical memory it still makes sense to run 64-bit OS and if you are going to run 64-bit OS you may as well run 64-bit DB2 Express-C.

But why??
