Blaming bad code won't help you find performance bottlenecks and improve the speed of your Java apps, and neither will guessing. This article directs your attention to tools for Java performance monitoring, Here's five tips for using Java 5's built-in profiler, JConsole, to collect and analyze performance data.
Remote MySQL Performance and Query Monitoring
There may be the situation that you have to monitor a MySQL
server remotely. There are some linux tools to do performance and query
monitoring locally, and these tools can also used to monitor remotely -
but only unencrypted !

Facebook engineer Sean Lynch has built a mind-blowing, custom server-monitoring tool for the company that uses heat mapping to keep tabs on a huge number of servers at a glance.
Lynch is part of the cache performance team at Facebook. When things go wrong he needs to know quickly whether problems are being caused by caching or something else.
Although not as popular as top or htop, nmon is still one of the best monitoring tools for Linux. Nmon is a tuner, benchmark and system administrating tool. Nmon displays many system performance info cpu, memory, hard drive, network .. By default, nmon updates output data once every two seconds. However, you can easily change this interval to any time period that you prefer.
If this question is at the wrong forum, be free to tell me. I'm a c# developer, but I'm running in a system management issue here.

Nowadays, high-performance server software (for example, the HTTP accelerator) in most cases runs on multicore machines. Modern hardware could provide 32, 64 or more CPU cores. In such highly concurrent environments, lock contention sometimes hurts overall system performance more than data copying, context switches and so on.
I am currently performing various development tasks that are slow on my current system because of IO performance.
Is there a way to record disk operations while performing IO consuming tasks, including performance info (writes/second, reads/second, etc) and then replay them on a new system to see which would the performance be there (without having to re-run the same command over the same set of
