What's Your Xfce4 Memory Utilisation Like?

[iamasmith]

Hi,

I'm just wondering what memory utilisation you are seeing in xfce4. I end up with about 2Mb free running OpenBSD with the full xfce4 environment running. Once a working set has been established for paging it is workable to run AbiWord etc but you do seem to see around 7 or 8Mb committed to the page file.

Thanks Albert, I don't see the session manager, taskbar or desktop manager loaded... I presume that was all a little heavy for pdaXrom too

I don't use desktop and my taskbar is integrated into the panel.

Thanks Albert but what we are seeing there are the process IDs and not the memory usage

[albertr]

Well, you are not easy to please
How bout the following:

Thanks Albert, yes memory usage looks about the same... I wondered if it was something related to the malloc buckets in OpenBSD that was causing excessive memory allocation... having said that I think that libc is resonsible for most application malloc buckets so both systems will look similar. (OpenBSD Kernel has malloc buckets too though).

I wonder if there's any milage in investigating libc and tweaking the buckets so there are granular steps.. it may be a way of reducing bloat in memory allocation on things like this..

hmmm...
