"To give you a few examples of some of the phenomenal improvements we got with LandlordMax, before we started using JProfiler, we ran a rent roll report that generated 521 pages of rents due (that’s a big database!) in less than 14 minutes. That seemed reasonable to us when you consider the size of the report. This same report now runs on my computer in 12 seconds!!! Yes you read that right, in 12 seconds! When we ran it with JProfiler, the performance bottleneck jumped right out at us. It was not at all where we thought it was, we had been focusing on the wrong area of code. Had we not used JProfiler for this, we could have spent many more hours, possibly days, trying to improve the performance and it would have only been minor, maybe we would have shredded one minute from the total time, nothing like what we achieved."

"JProfiler: What an amazing, essential tool! How could I ever have lived without it? Dear team, I have been using JProfiler for two days now and it has changed my way of thinking how to develop an application. Not only will I buy a license as soon as the trial expires but will tell *a lot* of fellow developers about it. Also, I want my day-time employer to get this for all of us developers there. I love the amazingly quick and simple integration with my servlet container (tomcat 5.0). Setup took - say - 1 minute and I could immediately evaluate my application from a much better level (than just assuming things) Thank you for building such a useful, easy-to-use and easy-to-understand tool. Very, very, very cool.

"I have evaluated lots of Java profilers. Yours is simply FAN-TA-STIC!. I love the 'live' views and auto-updated profiling information. JProfiler is also the only profiling tool to reliably report time spent in JNI calls, which is very valuable in our Java applications which are JNI intensive."

"I want to pass along some compliments since I always provide the technical questions. JProfiler helped us make our code about 4 times faster. We were discussing how much we like your product last night."

After evaluating multiple profiling tools, including the other well known programs and some not so well-known ones, only JProfiler enabled us to find the bottlenecks in a reasonable time with a reasonable performance.

"Jive Software conducted a thorough evaluation of Java Profilers. We were very impressed with ej-technologies' JProfiler and selected it as our profiling tool, finding it superior to other Java profilers available in the market today." (Jive Forums powers Sun's JDC and IBM's DeveloperWorks)

"We're very impressed with JProfiler. As well as offering comprehensive functionality, it has a great user interface and is very easy to learn. It is also completely reliable and stable, which is important for professional developers. Overall, it's a very slick product. We choose JProfiler after carefully evaluating several products. I can recommend JProfiler without hesitation as being best choice."

Andy Grove, CTO

"I bought JProfiler because I like its heap profiling much better than other tools. I'm doing a lot of memory intensive statistical model building, and it always surprises me where the memory goes, even though I built the statistical model that pretty well describes how things should go! My hat's also off to your programmers for making it so responsive."

"One of the things that really strikes me about JProfiler is that it's so easy to use. The main window is simple and intuitive, allowing you to quickly navigate between the different views on offer. Filters are also very straightforward and provide a way to focus on a specific set of information." (the entire review is available on Simon Brown's blog)

"JProfiler is an easy to use and nimble product that has helped us drastically reduce the time it takes to locate bottlenecks in our code."
