I have never got close to 1.8 on a 32bit OS, but then you also have to consider the memory usage in addition to the heap size. CF itself uses a bunch of memory as it is a java app, then there are the perm gen sizes and what not, so your max heap size will depend on other settings. I have never been able to set it much more than 1GB.
on 64bit you can use all the available memory but 64bit also uses about twice as much to begin with On Thu, Apr 3, 2014 at 11:04 AM, John M Bliss <bliss.j...@gmail.com> wrote: > > Sorry.
