Time To First Byte (TTFB) This is the time it takes for the first piece of information from the server to reach the user’s browser. You need to beware that slow server response times can significantly increase TTFB, often due to server overload, network issues, or un-optimized logic on the server side.

If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? Sysbench ran on a third server, which I’ll refer to as the application server (APP).

Hardware Memory The amount of RAM to be provisioned for database servers can vary greatly depending on the size of the database and the specific requirements of the company. Some servers may need a few GBs of RAM, while others may need hundreds of GBs or even terabytes of RAM. Benchmark before you decide.

Also, we will take a look at our open-source backup utility custom-built to help avoid costs and proprietary software – Percona Backup for MongoDB or PBM. Best practice tip : It is always advisable to use secondary servers for backups to avoid unnecessary performance degradation on the PRIMARY node.

Redis's microsecond latency has made it a de facto choice for caching. Four years ago, as part of our AWS fast data journey, we introduced Amazon ElastiCache for Redis , a fully managed, in-memory data store that operates at microsecond latency. However, the slots must be moved manually on the server side.

It’s a planet-scale client-server architecture with an enormous number of mostly thin clients sharing the services of a few giant server systems. It’s limited by the laws of physics in terms of end-to-end latency. We push as much data processing as possible onto warehouse-scale computers and systems software.

Yet, for all these technological developments, it’s interesting that many of us are still serving sites in the same way Tim did with the very first website — a web server serving static website files. It was a battle of not only proprietary vs open source but also static vs dynamic. But, when it worked, it was magical.

Cost is one of the key reasons why most government organisations, mid to large sized business, and publisher prefer open source CMS options such as WordPress and Drupal. In addition, open source CMS solutions also struggle with blotted plugin ecosystem. i.e. everything you need to render your site.

It is common to see a value of “ 0″ ( or sometimes “10” ) on database servers, telling the kernel to prefer to swap to memory for better response times. The CFQ works well for many general use cases but lacks latency guarantees. A setting of 100 determines it to swap aggressively to disk.

In the MySQL open source ecosystem, we have only two consolidated ways to perform sharding — Vitess and ProxySQL. One example could be using an RDBMS for most of the Online transaction processing ( OLTP) data shared by country and having the products as distributed memory cache with a different technology.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

This difference by itself doesn’t do all that much (it mainly reduces the overhead on the server-side), but it leads to most of the following points. Server Sharding and Connection Coalescing.
