Not that you'd want a sigle process to grow that large anyway. So what is the ceiling on 32-bit processors for RAM? Most of the 64-bit vendors are pushing Athalon64 and G5 as "breaking the 4GB barrier", and even I can do the math on 2^32. All these 64-bit vendors, then, are talking about the limit on ram *per application* and not per machine? This has all been academic to me to date, as the only very-high-ram systems I've worked with were Sparc or micros. -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
