CF9 dev server on Vista = 600MB memory?

Thanks guys for your response. I still don't really get it but I do see a performance difference with Vista/Server 2008 verses XP/Server 2003 in terms of memory usage. CF just seems to run better on the older OS. If this didn't cause a large drain on my laptop battery I wouldn't care. Oh well, looks like back to XP for me.

Thanks again!

The amount of virtual storage reserved by an application at any time can be quite large ... and yet, it doesn't matter one bit.  Here's why:

• Operating systems vary considerably in just how they go about arriving at such numbers.  Many resources are shared and, depending on what you are looking at, may be counted twice.
  
• In the absence of any actual memory-pressure, all operating systems will be "lazy."  They will not expunge things from memory without provocation, because someone might need it again soon.
  
• Applications may reserve "generously large" data structures because they know that only what is actually in-use will be paged-in (or even allocated), thus only it will be consuming system resources,

You do not have any actual problem until, under actual conditions of memory stress, the computer system starts spending too much time doing paging operations.  (If this happens:  "throw silicon at it.  Chips Are Cheap.")

CF will run with however much memory you tell it to run (in your jvm.config file).

However different OSes report memory usage differently.  What are you looking at to arrive at these various figures?

What memory settings have you got in your jvm.config file?

To be honest, I think the default jvm.config sets the Xmx size to 512MB (don't quote me on that), so by the time you add in various other memory allocations and consumption that the JVM is going to make, 600MB used up would be round about what I'd expect.  I certainly would not be raising an eyebrow.

[checks]

Yeah, each of my CF instances on Vista - both with an Xmx of 512MB, and maxpermsize of 192MB (which strikes me as being a bit high...) - consume about 600MB of RAM when running.
