Tile serving from dev has nearly come to a halt. the munin cpuusage stat
shows iowait at 87% and load at 6.
hdc1 is 89% full, whith hdd being close to empty.
1) Can we start to use hdd pretty soon to take some of the heat from hdc?
2) Why are they not combined to a (software) Raid0 for the main layer.
AFAIK, reads could then be distributed on both disks without the need to
introduce complex hash-based distribution of tiles on different disks.
3) Does dev really only have 1GB of RAM? Given it's increasing
importance of distributing,uploading,processing, and serving tiles, that
seams a little meager. Especially an increased disk cache might benefit
from more RAM. Are there plans to upgrade that and what would be the
estimated price for more RAM?
