[Opensim-dev] Will an SSD drive make OS any faster?

[Dahlia Trimble]

Once it's started and the regions have loaded, OpenSim is mostly memory
resident. One exeption is the local asset cache which may be frequently
accessed when new users arrive in a region and assets are delivered to them
(textures, etc.). This is often mitigated by each user's viewer cache
(assuming they visit the region frequently). I suspect if you have a region
with many unique textures and very many first time or infrequent visitors,
you might see an improvement by having your asset cache reside on a
high-speed storage device. Otherwise I'm not sure it would be of much
benefit at all over lower cost mass-storage options.

Grid services and databases may benefit from higher speed storage if your
user base is sufficiently large and active.
