 {{UBIK}} caches all the local content (which exist on the device) in the devices' memory for fast access. However, as the number of objects grows, the device might become less responsive because of the large memory consumption. Also, the initial loading will take a considerable long time. Certain optimizations are added to overcome these problems.
