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.

Figure 1: Comparison of widest CPUs in 2015 and 2025. Figure 2: Comparison of four ISA assemblies corresponding to the same C code These distance-based instruction sets eliminate the need for register-renaming hardware, thereby resolving the bottlenecks associated with traditional register-based architectures.

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

One question I’ve often encountered is, “Why do we need HTTP/3 so soon after HTTP/2, which was only standardized in 2015?” However, many other devices are sitting between the client and the server that also have their own TCP code on board (examples include firewalls, load balancers, routers, caching servers, proxies, etc.).

This was starting to look like a Windows file cache bug. Maybe something to do with multi-socket coherency of the disk and cache or ??? The next step was a custom C++ program that opened the just-linked exe and called FlushFileBuffers on it. failure rate. 7-second sleep after linking exes: 2% failure rate. Update, October 2018.

When a web crawler visits a server that has already rendered the content and pictures, indexing and caching of the content becomes quicker. When one needs to make complex calculations simultaneously, then Swift, Objective-C, and Java have more speed than JavaScript since there are overheads within JavaScript to control native elements.
