I work for a fairly large & well known company that ships a commercial version of Tomcat with the default heap size set to 512Mb. I regularly see heaps of 2Gb and more at work with customers. Quibbling about memory size because the number 'seems a bit large' is a waste of your customer and your own time. If they're not paying for you for the time you take to explain, just tell them it's normal & move on. p > thanks, again! > > -- > <http://www.reconcavo.org.br/> *CELSO DANTAS* > > *Pesquisa & Inovação > + 55 71 2101.4104 | skype: celsomdantas* > Antes de imprimir pense em seu compromisso com o Meio Ambiente. > > > > > On Wed, Jan 25, 2012 at 3:45 PM, André Warnier <a...@ice-sa.com> wrote: > >> Pid * wrote: >> ... >> >> >> >>> And of this, a Tomcat instance with just the ROOT application can be >>> observed to consume from ~6Mb to ~10Mb of RAM in the object heap with >>> a nice stable sawtooth on most systems. >>> >>> Not that I want to cast doubt upon your measurements, but somehow that >> seems hard to believe.
