In a previous post , we described how our TV application consists of a C++ SDK installed natively on the device, an updatable JavaScript user interface (UI) layer, and a custom rendering layer known as Gibbon. Our UI runs on top of a custom rendering engine which uses what we call a “surface cache” to optimize our use of graphics memory.

Aurora Parallel Query response time (for queries which can not use indexes) can be 5x-10x better compared to the non-parallel fully cached operations. The second and third run used the cached data. It does not use any cache (ie: innodb buffer pool) either. I will compare AWS Aurora with MySQL (Percona Server) 5.6

When a web crawler visits a server that has already rendered the content and pictures, indexing and caching of the content becomes quicker.
