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. AWS Aurora (based on MySQL 5.6)

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. India became a 4G-centric market sometime in 2018. The Moto G4 , for example. 2] Getting accurate global information that isn't artificially reduced to averages remains an ongoing challenge.

The Mozilla Internet Health Report 2018 states that — especially as the Internet expands into new territory — “sustainability should be a bigger priority.” An obvious metric here is CPU usage, but memory usage and other forms of data storage also play their part. These include data transfer (i.e.

To illustrate the data reads on Oracle we can flush the buffer cache. Consequently we now need to increase the buffer cache in size if we are to see more CPU activity. log 2018-11-02T15:39:25.628040+00:00 Thread 1 cannot allocate new log, sequence 1403.

Add onto that the yawning chasm between low-end and high-end device performance thanks to chip design factors like cache sizes, and it can be difficult to know where to set a device baseline. Time required to read bytes from disk (it’s not zero, even on flash-based storage!). Time to execute and run our code.

The idea is quite straightforward: Push the minimal code needed to get interactive for the initial route to render quickly, then use service worker for caching and pre-caching resources and then lazy-load routes that you need, asynchronously.
