Inventory Functional Spec

Performance Requirements

Will this feature affect:

• Client FPS? YES. Large inventories take longer to draw. (perhaps this is fixed)
• Simulator FPS? YES. Inventory is fetched from dataserver on the Simulator, so it may have a small effect on Simulator performance.
• Database? YES. The dataserver fetches inventor from the Database.
• Asset server? YES. Rezzing items reads from the Asset server. Creating invetory items writes to the Asset server.
• Network load? YES. The inventory structure must be streamed to you. Rezzed or opened items must be streamed to you. Uploaded items must be streamed to the asset server.
• Any other system? NO.
