Bernie's Performance Testing Blog: A model for understanding throughput
http://iperformax.blogspot.com/2009/12/throughput-mental-model.html
Bernie's Performance Testing Blog. Monday, December 7, 2009. A model for understanding throughput. I think a great mental model for understanding throughput and capacity planning is that of a highway and toll system. As the system approaches its capacity limit, the queue for the toll booth(s) will grow as cars wait for service. If you want to measure the throughput of the system, all you need to do is count cars as they leave the slowest resource, in this case the toll booth(s). Now we have a good mental...
Bernie's Performance Testing Blog: Using OpenSTA in the Amazon EC2 (part 1)
http://iperformax.blogspot.com/2009/12/opensta-in-amazon-ec2.html
Bernie's Performance Testing Blog. Monday, December 14, 2009. Using OpenSTA in the Amazon EC2 (part 1). EC2, what is it? Amazon Elastic Compute Cloud consists of leased computers running virtual machines. It offers virtually unlimited compute and network scalability, on the operating system of your choice, on demand, dirt cheap. Read more about getting started with EC2 here. OpenSTA, what is it? Why OpenSTA on EC2? Good, then lets get to it. The first step is installing the Elasticfox. This creates a sin...
Bernie's Performance Testing Blog: Response time statistics using SQL
http://iperformax.blogspot.com/2010/01/estimating-response-time-percentiles.html
Bernie's Performance Testing Blog. Monday, January 4, 2010. Response time statistics using SQL. I typically use Excel for statistical analysis of response times. Occasionally, for very large data sets, I use SQL. Here is some handy SQL to calculate min, max, average, std deviation, and 95th percentiles from response time data. The response time data for this example came from a test where I had established steady state periods of activity at 300, 600, 900, and 1200 virtual users. Graphing count vs VUs gi...
Bernie's Performance Testing Blog: Performance testing strategies
http://iperformax.blogspot.com/2009/12/bernie-velivis-on-performance-testing.html
Bernie's Performance Testing Blog. Monday, December 7, 2009. I posted this on the OpenSTA mailing list a year or so ago. I've seen it posted in a few different places since then, so why not here from the source. Get the system under test into a steady state and start failing components (servers, routers, etc) and observe how response times are effected during and after the failover and how long the system takes to transition back to steady state and you are on your way towards FAILOVER TESTING. (A gr...
Bernie's Performance Testing Blog: Using OpenSTA in the Amazon EC2 (part 2)
http://iperformax.blogspot.com/2009/12/using-opensta-in-amazon-ec2-part-2.html
Bernie's Performance Testing Blog. Thursday, December 17, 2009. Using OpenSTA in the Amazon EC2 (part 2). Continued from Part 1. The status of an instance changes to Running. The first step in configuring the new instances is to connect to the master node using RDP. One of the first things you will be greeted with is a message that the OpenSTA name server has exited and you will be asked if you want to send an error report. Just cancel the dialogs. Whats happening here? In the Repository Host. Field, cli...
Bernie's Performance Testing Blog: January 2010
http://iperformax.blogspot.com/2010_01_01_archive.html
Bernie's Performance Testing Blog. Saturday, January 30, 2010. A cool SQL trace analyzer. SQL server reports for top queries by total CPU and top query by average CPU showed one stored procedure using cursor processing was responsible for the majority of the CPU utilization. The stored procedure was modified to use more set processing and a few weeks later was QA'd and put into production. The result was disappointing. CPU utilization was barely changed. Whats going on here? Both the top query by average...

Bernie's Performance Testing Blog
Bernie's Performance Testing Blog. Friday, November 26, 2010. Pro tip: When searching for a needle in a haystack, use strong magnets. As luck would have it, a long delay occurred the second night of SQL tracing. Great! Now at least I have something to analyze. Lets see now, perf counters for 8 servers, all objects, 24 hours of data. Wow, what was I thinking? The reports are in HTML or XML format. You can view a sample here. Which I converted to PDF format for this post.). Than the Wright Flyer. PS - I'll...
