Which Java profiler is better: JProfiler or YourKit?
提问by Trenton
Which profiler is better for general purpose profiling and heap analysis? 90% of our apps are standalone command line programs with substantial database and numeric processing. The other 10% are webapps/servlet container apps (with very little JSP and NO SCRIPLETS!). Target user would be Sr Software Engineer with 5-10 years of industry experience. We need support only for Sun JDK 5 and.
哪种分析器更适合通用分析和堆分析？我们 90% 的应用程序是具有大量数据库和数字处理功能的独立命令行程序。其他 10% 是 webapps/servlet 容器应用程序（只有很少的 JSP 并且没有脚本！）。目标用户是具有 5-10 年行业经验的高级软件工程师。我们只需要支持 Sun JDK 5 和。
As of writing this question (2008-10-02), JProfiler was at 5.1.4 and YourKit was 7.5. Looks like YourKit 8.0 will be released soon.
在撰写此问题时 (2008-10-02)，JProfiler 为 5.1.4，而 YourKit 为 7.5。看来 YourKit 8.0 即将发布。

If you're on jdk >=1.6_07 you might also want to look at jvisualvm which comes bundled.
如果您使用 jdk >=1.6_07，您可能还想查看捆绑的 jvisualvm。

I've only used JProfiler (and some JProbe). As far as I can tell, one limitation of YourKit is that they don't appear to support JDK 1.4.2. That's not an issue for many people, but it might be.
我只使用过 JProfiler（和一些 JProbe）。据我所知，YourKit 的一个限制是它们似乎不支持 JDK 1.4.2。这对很多人来说不是问题，但可能是。

i've used yourkit and it is a verynice profiler, the best i've ever used in java (i've used a variety of others over the years). that being said, i've never used jprofiler, so i can't give a direct comparison.
我使用过 yourkit，它是一个非常好的分析器，是我在 Java 中使用过的最好的分析器（这些年来我用过很多其他的）。话虽如此，我从未使用过 jprofiler，所以我无法进行直接比较。

Been using JProfiler for years and very happy with it. IntelliJ seems to switch their recommendation back and forth between YourKit and JProfiler so I would guess their feature sets are similar. I believe they both have trial version.
多年来一直使用 JProfiler 并且对它非常满意。IntelliJ 似乎在 YourKit 和 JProfiler 之间来回切换他们的推荐，所以我猜他们的功能集是相似的。我相信他们都有试用版。

I've used both JProfiler 4 and YourKit 7.5, and YourKit wins hands down. It's so much less invasive than JProfile, in that I'll happy run production servers with the YourKit agent installed, which I would never do with JProfiler.
我使用过 JProfiler 4 和 YourKit 7.5，YourKit 胜出。它比 JProfile 的侵入性小得多，因为我很乐意在安装了 YourKit 代理的情况下运行生产服务器，而使用 JProfiler 则永远不会这样做。
Also, the analysis tool that comes with YourKit is more intuitive (in my opinion), making it easier to get the root cause of problems.
另外，YourKit 自带的分析工具更直观（在我看来），更容易找到问题的根源。

+1 for yourkit --- using 7.0 on dev boxes in windows
not used JProfiler for a while -- cannot comment since they might have improved in the meantime.
+1 for yourkit --- 在有
一段时间没有使用 JProfiler 的Windows 开发框中使用 7.0 - 无法评论，因为它们可能在此期间有所改进。

Just as an aside, you may want to consider the Netbeans profiler -- it's pretty good. But I've not used either of the two you mentioned.
顺便说一句，您可能需要考虑 Netbeans 分析器——它非常好。不过你说的两个我都没用过。

I have used YourKit. I have not used JProfiler. I have used OptimizeIt before. I have very good opinion about YourKit. It is very stable and good GUI and good feature list. One unique feature I have noticed is CPU profiling with and without wait time (like I/O wais) including.
我用过 YourKit。我没有使用过 JProfiler。我以前使用过OptimizeIt。我对 YourKit 有很好的看法。它非常稳定，良好的 GUI 和良好的功能列表。我注意到的一项独特功能是 CPU 分析，包括等待时间和不等待时间（如 I/O wais）。
It is priced also very reasonably (about about $1100 for 5 licenses I think)
它的价格也非常合理（我认为 5 个许可证大约 1100 美元）
