Triggered by current expected load projections for our community portal, our Apps Team was tasked to run a stress on our production system to verify whether we can handle 10 times the load we currently experience on our existing infrastructure. In order to have the least impact in the ...
Last month, I went to my engineering school, where I graduated 15 years ago, to attend the Annual Gala. While there, I met a few young engineers who asked about my job. This raised a question: “What would make them join my team?” In the IT world, the demand for highly skilled software...
If you’re a regular here, you know how much we care about the full-stack view of applications. Today, let’s zoom in a bit, and talk about the performance of a single layer. In particular, let’s look at profiling in Python. As an example, let’s take this bit of code for calculating con...
Foxconn is losing its Apple monopoly. Apple has signed up $7.4 billion-a-year Pegatron to build the low-cost iPhone it’s expected to bring to market later this year, according to the Wall Street Journal. Pegatron, which started making iPad minis last year and made some iPhones the ...

Complexity is the new reality of web and mobile applications with almost no new release going out without the addition of services and applications spread across many different companies. But the reality of this new interrelationship is still the same: If a third-party Internet outage ...
The saying “if it doesn’t exist on the Internet, it doesn’t exist”[1] is ringing truer every day. Nowadays, it is hard to imagine most businesses without an e-commerce platform, let alone without a web presence at all. Since e-commerce is becoming the new standard, e-commerce performan...

Here at AppNeta, we get to see a lot about how people build their web applications. From simple PHP scripts to heavily service-oriented Java clouds to monolithic Django apps, everybody’s product is architected a little differently. We’re still out to trace everything, and today I want ...
Boston-based Cloudant and its NoSQL distributed Database-as-a-Service (DBaaS), which have gone to the VC trough four times since the company was started in 2008, have gotten what appears to be their first real money to grow on: a $12 million B round led by Devonshire Investors, the pri...
Adding more memory to your JVMs (Java Virtual Machines) might be a temporary solution to fixing memory leaks in Java applications, but it for sure won’t fix the root cause of the issue. Instead of crashing once per day it may just crash every other day. “Preventive” restarts are also j...
This review covers both Core Java Volume I--Fundamentals (9th Edition) and Core Java, Volume II--Advanced Features (9th Edition). Both books are part of the Prentice Hall Core Series. I actually got Volume II first and liked it so much I ordered Volume I. I felt like I was missing the...
Back in the misty eons of time, it used to be easy to measure the performance of your application. You’d grab a stopwatch, load up your web application, and see what happend. If it was slow, you’d look at the mess of PHP, HTML and CSS you crammed into index.php and make sure that you w...
A question that every online application provider will face eventually is: Does my application scale? Can I add an extra 100 users and still ensure the same user experience? If the application architecture is properly designed the easiest way is to put an additional server behind the l...

I started my career as a Telecom Engineer for Rational Software in the load testing space back in the late ’90s, and when I look back on the last decade, there were enormous advances in the broader IT world including development methodologies, processing speeds, network speeds, mobile ...
Things are moving fast for the Ruby language instrumentation in TraceView. We already support tracing of memcache-client, memcached, dalli, mongo, moped, mongoid, mongomapper, cassandra, ActiveRecord (postgres, mysql, mysql2) plus more. Most recently we added support for Rack and Resqu...
When you look at the database market, it’s a virtual jungle out there. Those of us in the industry 15 years ago can look back and remember when we only had the option to use a relational database from Sybase, Oracle, Microsoft or IBM. That was pretty much it if you were planning to bui...
Over the last couple of months I have been talking to more and more customers who are either bringing their Hadoop clusters into production or have already done so and are now getting serious about operations. This leads to some interesting discussions about how to monitor Hadoop prope...
There suddenly seems to be a run on API management start-ups. First Intel acquired Mashery. Then CA bought Level 7. Now six-year-old 3scale of Barcelona and San Francisco has gotten $4.2 million in funding from Javelin Venture Partners and Costanoa Venture Capital. The round is meant...
Our fundamental unit of performance data is the trace, an incredibly rich view into the performance of an individual request moving through your web application. Given all this data and the diversity of the contents of any individual trace, it’s important to have an interface for under...

Hibernate is one of the most used ORM Java frameworks out there. It is really simple to use, just add few annotations and you’re ready to go. However, it is also really easy to experience strange behaviors and bugs if you don’t respect Hibernate’s best practices. That’s why at Tocea we...
Last week, I presented Caching Up and Down the Stack at the Boston Web Performance meetup. It was great to get the chance to present to the 60+ people who came out for the talk. Unsurprisingly, many of the people there knew a lot about caching in all of the different levels I touched o...
Over the past two decades relational databases have been most successful in serving large scale OLTP and OLAP applications across enterprises. However, in the past couple of years with the advent of Big Data processing, especially for processing unstructured data coupled with the need ...
I’m excited to announce a new feature to TraceView – the Data API. In a nutshell, the Data API exposes all of those high-level metrics you’re collecting in TraceView over REST, formatted as JSON. Now you can take that data, jam it into your own system and do whatever you need to make ...
The easiest way to make your code run faster is to do less. At some point, though, you don’t want to do less. Maybe you want to do more, without it being any slower. Maybe you want to make what you have fast, without cutting out any of the work. What then? In this enlightened age, the ...
I started in the web performance industry – well before Application Performance Management (APM) existed – during a time when external, single page measurement ruled the land. In an ecosystem where no other solutions existed, it was the top of the data chain to support the rapidly evol...

Abstractness is a measure of the rigidity of a software system. Higher the abstraction, lower the rigidity (or greater the flexibility) and vice versa. And the stability is a measure of tolerance to change as in how well the software system allows changes to it without breaking it. Thi...
“The cloud (whether public or private) is a strong driver of Big Data,” noted Michael Kopp, a technology strategist at Compuware, in this exclusive Q&A with Cloud Expo Conference Chair Jeremy Geelan. “A Cisco survey said that 4 out of 5 IT professionals stated that ‘all or some Big Dat...
There is little argument at this point that the mass adoption of mobile technology and bring-your-own-device (BYOD) strategies by enterprises is a true business technology revolution. At the core, the catalysts driving this revolution are the vast array of mobile devices leveraging soa...
Mozilla CEO Gary Kovacs will be stepping down sometime later this year he told employees Thursday. Mozilla will be looking for a new chief executive and Kovacs will stay there until that person is found. He wants “something more commercial” to entertain him and will stay on the boa...
