The Console.time and Console.timeend methods allow developers to use in arbitrary code, and the result shown is the intermediate duration, in milliseconds. Because JavaScript performance is more and more important, it is useful for programmers to understand basic benchmarking techniques. One of the simplest benchmark tools is the console.time and console.timeend combination.
Console.time starts a timer. Instead, Console.timeend stops the timer and wr

Second wave: PostgreSQL
If TokuMX makes me feel that MongoDB is irrelevant, PostgreSQL 9.2 strengthens this impression. Since version 9.2, PosetgreSQL has supported JSON and JSONB data types. This is an interesting solution because it gives me a better idea of document flexibility in the relational model. All of these are based on the same product. Great!

with very simple tools to perform high-concurrency inserts or read tests as clients. MongoDB itself is a high-performance database, and the concurrency can be up to tens of thousands of levels per second in the case of proper tuning. If the client's code is simple and brutal, and even uses a single-threaded client, the bottleneck in performance testing is first in the client itself, not the server. So choosing an efficient client is an important firs
