In this tutorial, we will see how a Ruby interpreter with different servers performs under load. The tutorial steps assume a fresh Ubuntu 13.10 x32 image. The results were obtained from a 512 MB droplet.
ngx_pagespeed, or just pagespeed, is an Nginx module designed to optimize your site automatically by reducing the size of its resources and hence the time the clients’ browsers need to load it. This article will guide you through the installation and configuration of the pagespeed module for Nginx.
Learn how to configure Nginx access and error logs and set up log rotation on Ubuntu to prevent disk issues and improve monitoring.
Memcached is an in-memory key-value cache that can be used to temporarily cache frequently requested data on websites. In this guide, we will demonstrate how to install and use memcached on an Ubuntu 14.04 server.

HAProxy is an open source software which can load balance HTTP and TCP servers. In the previous article on HAProxy we configured load balancing for HTTP and in this one we’ll do the same for MySQL. All your MySQL servers have to be configured to perform Master-Master replication as load balancing involves both reading and writing to all the backends.
ngx_pagespeed, or just pagespeed, is an Nginx module designed to optimize your site automatically by reducing the size of its resources and hence the time the clients’ browsers need to load it.
Continuous use of SSDs results in degraded performance if not accounted for and mitigated. The TRIM command is an operation that allows the operating system to propagate information down to the SSD about which blocks of data are no longer in use. This allows the SSD’s internal systems to better manage wear leveling and prepare the device for future writes. Continuous TRIM is possible, but can negatively impact performance. Scheduled, periodic TRIM is a good alternative in most cases.
Apache mod_spdy is an open source Apache module that allows Apache web servers to serve HTTPS requests using the SPDY protocol. SPDY (pronounced as “SPeeDY”) is a new protocol created to address speed related problems with the HTTP protocol; it allows the client and server to pass multiple requests over a single connection, compress request and response headers, and all the server to push site resources to the client without the client requesting them.
ProxySQL is a SQL-aware proxy server that can be positioned between your application and your database to create a caching layer to optimize MySQL queries. In this tutorial, you will use ProxySQL to set up transparent caching for a MySQL server on Ubuntu 16.04. You will then test its performance using mysqlslap with and without caching to demonstrate the effect of caching and how much time it can save when executing many similar queries.
