Do I need more RAM?

[Mark Phillips]

I have a Zope/Plone 2.5 web site running on Debian on a Linode virtual host.
It has grown over the last few years, and now I need to add some more disk
space. The site is for a school newspaper, so from August - June, students
add news articles and photos.

I was also looking at the output of top, and perhaps I need more RAM as
well? Top shows I have only 5 MB free out of 368 MB of total RAM, but I am
only using 9% of my swap, so perhaps I don't need more RAM. The site does
not seem slow.

Tasks:  69 total,   1 running,  68 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,
0.0%st
Mem:    368836k total,   363364k used,     5472k free,     8316k buffers
Swap:   524280k total,    46716k used,   477564k free,    67436k cached

Thanks for any suggestions you may have.

Mark
