It has been reported that p.o. administration of diallyl sulfide (DAS), a naturally occurring component of garlic (Allium sativum), inhibits 1,2-dimethylhydrazine-induced colon and liver cancer in rodents. A possible mechanism for this protective effect is inhibition of hepatic activation of the procarcinogen. The effect of DAS on P450IIE1, an isozyme of(More)
Many times load testing is dismissed as a waste of time and money because past results didn't conform to real world experience when the application went live. Sometimes it's because the test suite is too narrow but often it is due to the approach used to produce traffic and the way results are interpreted. This discussion focuses on the latter situation(More)
Conventional load-testing tools are based on a fifty-year old time-share computer paradigm where a finite number of users submit requests and respond in a synchronized fashion. Conversely, modern web traffic is essentially asynchronous and driven by an unknown number of users. This difference presents a conundrum for testing the performance of modern web(More)
This is a follow-up to my CMG'12 presentation titled " When Load Testing Large User Population Web Applications the Devil is in the (Virtual) User Details " , [BRAD2012]. During my talk I mentioned that most load tools do not offer a Negative-Exponential distribution timer option, even though it is the logical one to draw think times from when attempting to(More)
A common server configuration that has emerged for supporting Web based applications is the Web Server, Application Server, and Database Server arrangement. This paper discusses a specific traffic capacity testing experience with this server combination for a Windows ® environment using a transaction oriented load generator instead of a traditional virtual(More)
