style="FONT-STYLE: normal; DISPLAY: inline; FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: small; FONT-WEIGHT: normal; TEXT-DECORATION: none">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.<BR><BR>Grid services and databases may benefit from higher speed
storage if your user base is sufficiently large and active.<BR><BR><BR>

be expensive... I'm basically going to pour my money into a nice quad core CPU
and RAM. But, I wanted to know if anyone here has any experience running OS
using a high speed drive such as Seagate's Cheetah or SSDs. I'm really
interested to hear if anyone has any experience with SSDs as they seem to be
the fastest in terms of retrieval and storage.<BR><BR>My theory is that OS is

so, would and SSD drive help?<BR><BR>TYIA!<BR><FONT color=#888888><BR>David
