Ok, good to know.

Oh... well I wish I had communicated more often earlier on. I just did
this to test the feasibility of the project. The in-memory partition has
grown into the full fledged partition I'm currently using. When I switch
to 1.5 I'll see about piecing it back together into an in-memory one. 
Note: it was not too special - not all methods were implemented just 
add/delete/update capability and had a number of limitations..

I'll send the results of future profiling results. I'll try to profile 
with multiple simultaneous clients.

Excellent response. Thanks to everyone here for creating ADS. ADS looks 
very well engineered and I look forward to participating as well as 
using ADS in commercial projects.
