Open-Source Web Servers: Performance on a Carrier-Class Linux Platform
ARIES started as a proof-of-concept project to study if we could build an internet server that has near telecom-grade characteristics using Linux and open-source software as the base technology. We have experimented with the various Linux distributions, web and streaming servers, traffic distribution and load-balancing schemes, distributed and journaling filesystems suitable for HA Linux clusters and redundancy solutions (NFS, Ethernet, Software RAID).
For the future, the work in ARIES will be directed toward augmenting the clustering capabilities of Linux to enable the system to accommodate more types of mobile internet services in addition to the already deployed web server applications looked at thus far. The focus will be to enable the system to reach the optimal utilization of the cluster's resources and to enhance the security aspects required within a mobile internet server. In addition, the project will augment the capabilities of the existing systems by supporting IPv6 technology.
We are keeping all three web servers on our experimental Linux cluster platform. The tested web servers did not scale linearly as we added more CPUs. However, they demonstrated very good performance and near-linear scalability (testing was limited to 12 CPUs). We are currently deploying the latest versions of Apache (2.0.15a), Jigsaw (2.2.0) and Tomcat (3.2).
Based on our tests, we believe that Apache has shown to be considerably faster and more stable than other web servers. We are looking forward to testing and experimenting with the 2.0 release version, which promises a clean code, a well-structured I/O layering and a much-enhanced scalability.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.
Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

This great work needs updating
There's a FREE Web Server which is faster than all others, up to:
25x faster than Apache
20x faster than nginx and Rock (webspec's 2008/2009 winner)
400x faster than PHP, 200x faster than Python
With TrustLeap G-WAN, organizations can use much less computers
(and electricity) to achieve the same works:

Very useful article - however, comparing Tomcat and Apache is like comparing apples and oranges: Apache is designed to serve static content, while Tomcat is primarily a JSP/Servlet engine, and contains a standalone web server as a convenience.
Apache 2.0 threading
Good article. Would like to know if Apache 2.0 was set up in this test to run threaded, or multi-process. The
similarity in performance makes me think both Apache 2.0 and 1.3 versions were running multiple Apache processes, with
resulting overhead from spawing new processes. Under Linux this isn't huge, but other unices have problems with
this model.
I'm also interested in Apache 2.0's multithreded performance when running as an app server - mod_perl, mod_php or
mod_python for example. Does threading allow sharing of persistent database connections, and what effect does that
have on memory usage, speed, and behaviour under heavy loads?
Re: Open-Source Web Servers: Performance on a Carrier-Class...
I'm very pleased we got to run an article like this. This is our best defense against FUD from vendors of "less capable" web servers. When I got into Linux I never expected to see IBM running TV ads about Linux but what we see here shows me that IBM (and the rest of us) are on the right team.

a very useful article.
