Channel Deployment Issues for 2.4-GHz 802.11 WLANS

an investigation by cisco into some of the details of interference. over my head in places, but what i followed i found interesting.

in my apartment there were enough people on the default channels that i was unable to connect to my ap from a few feet away. i changed to a channel that looked empty and have had decent connectivity since. i didn't do a follow-up investigation, but came away from the experience with the feeling that it's better to try to fit in the spaces between when there are a lot of people on the defaults.

n.b. this is anecdotal and i am not a wifi expert by any means...

"The most important factors in determining swap space size are the requirements of the system's software applications. [...] If you are unable to determine swap space requirements from your application vendors, use the following general guidelines based on your system type to allocate swap space."

Workstation with about 4 Gbytes of physical memory: 1 Gbyte Swap

Mid-range server with about 8 Gbytes of physical memory: 2 Gbyte Swap

High-end server with about 16 to 128 Gbytes of physical memory: 4 Gbyte Swap
