Rick, Could you share the source of this information? I am extremely interested as we are getting "out of memory" errors on our mid-tier and one of possible solutions is to migrate to 64 bit (although we are on Windows)
Thanks Jiri Pospisil From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Rick Cook Sent: 29 June 2011 16:33 To: arslist@ARSLIST.ORG Subject: Re: ARS 7.6.0.4 Midtier and ARS 7.1 Server ** Jeff, are you sure you need the extra heap space the 64 bit Java will give you? BMC states that the 32 bit jvm is about 45% faster than the 64 bit. Your choice, just want to be sure you see the cost from both sides.
