Jprofiler vs yourkit code#
I’d suggest against this because this is very time consuming, error prone, has the high probability of introducing unncessary bugs, and adds a lot of extra code to your application.Ī better solution is to use a code profiling application. that would continually post information out to the screen. So where does this leave us? How do we do this? We could integrate within our application a bunch of timers, memory readouts, etc. It’s not! Often where you think there’s a bottleneck is just plain wrong. How do we do this? Most people will think that you just look at code, it should be obvious. So what we’re left with is focusing on the main performance bottlenecks. For example, if a screen refreshes in 10ms versus 20ms, no one will notice, it’s too fast to be perceptible, even if it’s a doubling in speed! However the cost of this improvement may be significant, hence driving up the cost of the software! No one wants this, and there’s no real benefit to anyone in this case. Most of the improvements you’ll do won’t make any noticeable difference. But more importantly, it’s often a waste of time and money. So then the question becomes, why not just optimize everything? Because that’s incredibly time consuming and very expensive. Lately we’ve been really pushing the envelop, creating databases that are larger than any of our customers will ever have, and we’ve noticed some performance issues with these massive databases, as well as some memory issues. When we initially ran our tests, we ran them with fairly large databases, but we’d only test one section at a time. As some of you may have noticed, we’ve really been pushing performance enhancements recently (for example: here and here), and there’s a reason why. Yes, that’s partially true, but not always! For LandlordMax, as the database becomes progressively larger, so does the importance of running a code profiler.
You would think that with today’s amazingly fast machines you wouldn’t need to worry so much about performance or memory (threading is something you always have to worry about).
Jprofiler vs yourkit software#
So in other words, it’s a tool that helps you find where your own software needs the most improvement. And surprisingly, a lot of software developers have no idea what a code profiler is!Ī code profiler is a software application that helps you find performance bottlenecks, pin down memory leaks and resolve threading issues in your software application. If you’re a software developers, absolutely!!! No doubt about it!īefore I go on, let me just take a step back to explain what a code profiler is to those that aren’t familiar with the term since a lot of you here also aren’t software developers.
