...Using booster, the stability of application can be increased by 15% ~ 25%, and the package size can be reduced by 1MB ~ 10MB. Potential performance issues could be found by using Booster, for example, calling APIs that may block the UI thread or main thread, such as I/O APIs. Thread management has always been a problem for developers, especially the threads started by third-party SDKs, starting too many threads may cause OOM, fortunately, these issues can be solved by Booster.

Stochastic Performance Logic (SPL) serves for capturing performance assumptions. With SPL, it is possible to annotate Java functions with assumptions stating, for example, that the annotated function is at most three times slower than array copying. The assumption is then checked at build time in a similar way as standard unit testing. In other words, SPL is about introducing performance assert(). The advantage of SPL in comparison with other similar solutions includes following. SPL formulas uses well-defined logic and statistically sound testing (such as t-test). ...

...Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. To see ngx_pagespeed in action, with example pages for each of the optimizations, see our demonstration site. PageSpeed improves web page latency by changing the resources on that web page to implement web performance best practices.

SeaToad is a library to aid in concurrency and load testing of .NET code. Intended for use by developers or automation testers. For example, it makes a good second hand if you're trying to reproduce a concurrency issue. You can very quickly generate load representing one or more portions of the suspect code, while manually performing other tasks. Or perhaps you're worried about the performance of a particular stored procedure with load from an external source. SeaToad can run the stored procedure and the external load for you to locate performance and concurrency bottlenecks.
