Open Source Squid Alternatives For Mac
Web performance is nothing but the speed in which web pages are downloaded and displayed on the user’s web browser. Faster website speeds have been shown to increase sales or increase visitor loyalty including user satisfaction. Particularly useful for those use slow internet connections or on mobile phones/tablets. You can increase the speed of page load using:
- Server side cache
- Browser side cache
- Faster disks
- Image optimization
- Web application accelerator focusing on optimizing caching and compression
- Load balancing and SSL offloading
- Geo or DNS-based load balancing and more.
Mozilla Firefox is an open source browser. Mac users can get it online at zero cost. Released in 2004, Firefox challenged the dominance of Internet Explorer. Today, more than half a billion people use it worldwide making it the second most popular browser globally. Its strength lies in its speed, reliability and the availability of useful extensions.
Its many features include enabling the simultaneous browsing of multiple pages with its tab system, supporting most existing web standards, and offering a personalized experience with extensions, plugins, and themes created by the community.The latest installment is focused on improving its technical aspects, so the appearance is almost the same as in previous versions. 
Mozilla continues to work on further improvements for its flagship product: the free and open source browser, Firefox.
In short, one can increase the time it takes for pages to render using multi-layered cache and asynchronous communication with server-side components. In this post, I will list my favorite open source software based TCP/HTTP load balancer and proxying solution for web performance.
Varnish – HTTP accelerator
Varnish Cache is a web application accelerator. You install it in front of any web-server that speaks HTTP and configure it to cache the contents. It act as a web application accelerator focusing on optimizing caching and compression It is really fast and used by high traffic websites such as Wikipedia, Facebook, Twitter and others. Varnish claims to delivering 20 Gbps on regular off-the-shelf hardware.

HAProxy – Load balancer and proxy server accelerator
HAProxy is an open source software based load Balancing, SSL offloading and performance optimization, compression, and general web routing software. HAProxy is used by some high-profile websites including GitHub, Reddit, and is used in the OpsWorks product from Amazon Web Services. I have seen healthy system can achieve between 15000 and 30000 hits per second, and have no trouble saturating a 2 Gbit/sec connection. HAProxy claims to delivering 10GbE load-balancing or more.

Squid – Caching proxy server
Squid is an open source caching and forwarding HTTP web proxy for the web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. Squid works with both LAN and WAN based application. You can often find the LAMP setup with Squid as a web cache. A high-performance and high-availability solution for a hostile environment.

Nginx – Reverse proxy, load balancer, HTTP cache, and web server
Nginx is an open source and free web server, which can also act as a reverse proxy, load balancer, SSL offloading, and HTTP cache. Nginx was found to be the second most widely used web server across all “active” sites on the internet. Nginx was written with an explicit goal of outperforming the Apache web server.

relayd – Load-balancer, application layer gateway, transparent proxy, and SSL/TLS gateway.
The relayd project provides a FREE implementation of a secure web engine that consists of relayd and httpd. relayd first appeared in OpenBSD 4.1 to provide a service that helps Server Load Balancing (SLB) with OpenBSD’s Packet Filter (pf). It was written by Pierre-Yves Ritschard and Reyk Floeter. The HTTP server, httpd, first appeared in OpenBSD 5.6 and was based on the code of relayd. The development is an an ongoing effort by Reyk Floeter, Sebastian Benoit, Florian Obser and various contributing OpenBSD hackers. Datamax e4203 printer. The software is used by some large sites and has also been ported to other operating systems.

Apache traffic server
Apache Traffic Server software is a fast, scalable and extensible HTTP/1.1 compliant caching proxy server. Formerly a commercial product, Yahoo! donated it to the Apache Foundation, and it is now an Apache TLP. Here’s a Traffic Server overview. This software improves network efficiency and performance by caching frequently-accessed information at the edge of the network. This brings content physically closer to end users, while enabling faster delivery and reduced bandwidth use. Traffic Server is designed to improve content delivery for enterprises, Internet service providers (ISPs), backbone providers, and large intranets by maximizing existing and available bandwidth.

Pound
The Pound program is a reverse proxy, load balancer and HTTPS front-end for Web server(s). Pound was developed to enable distributing the load among several Web-servers and to allow for a convenient SSL wrapper for those Web servers that do not offer it natively. Pound is distributed under the GPL. Quite a few people have reported using Pound successfully in production environments. The largest volume reported to date is a site with an average of about 30M requests per day, peaking at over 600 requests/sec.
