[Ginp-developers] Scalability and PicCollections

[Justin <ju...@sq...>]

Doug,

	I was looking through the Ginp sourcecode and I saw that a major 
scalability issue is that the PicCollections are loaded for each session 
that looks at them and then serialized and loaded on each web request. 
The best fix here is to use the flyweight pattern:

So we have ONE in memory collection of pics that all sessions use and 
their extrinsicState (The customization for each user) is passed into 
them from the client request for each operation.  This is probably good 
to do at the same time as the database integration.   I'll be taking a 
look at this today.  In the meantime I did a bit of work on the 
GinpServlet today.

Regards,

	Justin
