What about xload?
No. The RSS includes shared libraries, which compromise about 1M of the address space in an average X client.
The X server number is inaccurate too, since it also includes the memory mapped frame buffer (usually 4M).
>Is netscape really using 19 MB?
Yes. Netscape is a poorly written memory pig (ie, graphics are stored internally with the color content of the visual, irregardless of their size and color content (a multi-megapixel B&W image, like a digitized fax, could still get 4 bytes per pixel).
