提问by ripper234
List your favorite heap analysis tools (e.g. jprofiler, jmap, ...). Let's keep it one tool per answer, with a short list of pros and cons for each tool.

Pros:
优点：
- The interface is clean and it's fast
- It opened a large 5-gig heap dump where jProfiler grined to a halt. And it only needed 1-2 gigs of JVM ram to do so.
- 界面干净，速度快
- 它打开了一个大的 5-gig 堆转储，jProfiler 笑着停了下来。它只需要 1-2 个 JVM ram 就可以做到这一点。
Cons:Of course... it's not free :(
缺点：当然......它不是免费的:(

BHeapSampler http://dr-brenschede.de/bheapsampler/
BHeapSampler http://dr-brenschede.de/bheapsampler/
- generates a class-level heap-graph as a really intuitive display of the dominant memory structures
- can process really large heap dumps
- command-line tool, usable on server side without transfering the dump to the developer's desk
- 生成一个类级别的堆图作为主要内存结构的非常直观的显示
- 可以处理非常大的堆转储
- 命令行工具，可在服务器端使用，无需将转储传输到开发人员的桌面
