Min. system requirements for running Cumulus (my experience)

Post by hvalentim »

I thought it might be of interest to let you know that I am happily running Cumulus 1.94 beta on a Pentium MMX 200MHZ with 128MB Ram and Windows XP Pro 32bits SP3.

Memory usage is around 29 MB and CPU peaks to 80% for around 27 seconds while updating/uploading the web files and wunderground (see graph).

Which is curious since on Windows 7 64bits I get 70MB of memory usage :)

That's useful to know. I have tried to keep resource usage low, but inevitably it increases with each version (and also with different version of the compiler).

Where are you seeing the memory usage in Windows 7? I run Cumulus on Windows Home Server 2011, which is the same kernel as Windows 7 x64, and I have pretty much everything that might use memory turned on, and it's using about 35MB, according to Task Manager.

Actually I was quoting the figure delivered by <#AllocatedMemory>. If I open the program right now and it just sites there idle (no station connected) I read 26MB with Process Explorer.

Yes, the <#AllocatedMemory> value can be misleading; it's the amount of memory that the program could immediately call upon if it needed it, it doesn't mean it's actually using that amount of memory - the memory would be available for reallocation to a different process if it needed it.
