ANTS Performance Profiler is a.NET profiler for desktop, ASP.NET, and ASP.NET MVC applications. NEW: Profile your SQL queries and see execution plans Find performance bottlenecks fast by profiling both the.NET code and the data access layer. ![]() I just downloaded the trial version of and am investigating some of my team's code. Immediately I notice that there's a particular section of code that ANTS is reporting as eating up to 99% CPU time. I am completely unfamiliar with ANTS or performance profiling in general (that is, aside from self-profiling using what I'm sure are extremely crude and frowned-upon methods such as double timeToComplete = (endTime - startTime).TotalSeconds), so I'm still fiddling around with the application and figuring out how it's used. But I did call the developer responsible for the code in question and his immediate reaction was 'Yeah, that doesn't surprise me that it says that; but that code calls SignalAndWait [which I could see for myself, thanks to ANTS], which doesn't use any CPU, it just sits there waiting for something to do.' He advised me to simply ignore that code and look for anything ELSE I could find. My question: is it true that SignalAndWait requires NO CPU overhead (and if so, how is this possible?), and is it reasonable that a performance profiler would view it as taking up 99% CPU time? I find this particularly curious because, if it's at 99%, that would suggest that our application is often idle, wouldn't it? And yet its performance has become rather sluggish lately. Like I said, I really am just a beginner when it comes to this tool, and I don't know anything about the WaitHandle class. So ANY information to help me to understand what's going on here would be appreciated. ![]() This is a showcase review for our sponsors at The Code Project.

Introduction Not much has changed in terms of users' requirements for a high-performing application over the past two years since I last reviewed ANTS Profiler. Certain aspects of development have become simpler, while others have introduced new degrees of complexity. One thing is for sure, though: developers still face considerable challenges when trying to determine and improve the performance characteristics of their applications. Luckily, ANTS Profiler has evolved with the technology to provide a quick and easy way of identifying performance bottlenecks within your.NET applications. Version 3 is the latest version of and provides more features and full support of the current.NET runtime. What to Profile The CLRProfiler concentrates only on the profiling of memory within your application, whereas ANTS Profiler can profile both memory and time-related performance in your application. Ninja storm 3 all characters crack. The standard version of ANTS Profiler that I will be reviewing here provides metrics around duration and time-based performance. It's worth noting that ANTS Profiler Professional edition also deals with memory profiling. In my review of a previous version of ANTS Profiler, I compared the tool with the CLRProfiler. Rather than perform another comparison here, I can confirm that the results of that comparison are still valid. That is, ANTS Profiler provides a quicker and easier method to identify performance bottlenecks within your application. This is not to say that the CLRProfiler should not be used, but rather used in conjunction with ANTS Profiler. The slowest areas in your application can be identified very quickly with ANTS Profiler. The CLRProfiler can then be used to 'deep dive' into the convoluted aspects of memory management within that particular area of your application. Memory usage and performance are very tightly related in.NET application, and one should not be investigated without considering the other.
