[MapProxy] hardware requirements

[Anne Blankert]

Hello Christian,

I think a pretty modest server suffices.
Mapproxy uses very little CPU.
Disk IOPS is low, because MapProxy serves full tile files which is much 
easier to deliver than for instance database index data.
You may need a lot of disk space, because tile sets can be huge. If you 
are using a linux file system, remember to format the disk with enough 
inodes. On a default formatted disk, you may run out of inodes way 
before you run out of disk space.

Of course, if you expect to deliver millions of tiles per hour, you 
should provide the necessary resources for that, but you may discover 
that the internet bandbwidth will be the major bottle-neck in delivery 
performance.

For resource calculation consider:
1. wat is the expected total number of tiles ? => disk space and inodes
2. how many tiles should be delivered per minute at peak moments? => 
number of tiles x average tile size / 60 sec = bandwidth (bytes / sec)
3. peak minute number of tiles / 60 sec = maximum average disk seek time
