tivoli application performance management

【Abstract] Database applications based on WEB technology are a hot topic of current applications. Improving the Performance of web servers is an urgent issue when the number of users and communication load are high. Starting from the author's experience in the development of a banking system project, this article describes how to improve the performance of web servers to all aspects of project demonstration

(GC) mechanism and give the appropriate optimization strategy. Skyover at 2007-7-02 10:51:09 We talked about how to improve our rails application performance by optimizing Ruby code, so let's take a closer look at Ruby's memory management and garbage collection mechanisms.First, since Ruby's original design goal was to become a batch language like Perl, its memo

loading, short transactions, timely release, etc. (for most companies and developers, The problem with performance is more of a blind guess and scratching. But what are the shortcomings of these methods? At a glance, it can only be done in the test or production environment, causing the problem and making it clear. The test environment is fine, but if it is a production environment, the post-processing can be remedied, but most of the complaints are

acceptable and even necessary. For example, use some old libraries to interact with the hardware, the operating system, or to improve the performance of the program. The JNI standard ensures that the local code can work in any Java Virtual machine environment at least.2. What is the NDKThe Android NDK was added in front of the SDK with the word "native", the native development Kit, which Google called the "NDK".As is known to all, Android programs ru

performance is good, individual function delay is very long c) emerging problems? Since when did the system change? (Significant increase in upgrade or management resources) d) irregular problems? Sometimes fast, sometimes slow, no specific rules What are the metrics for performance? How many seconds, now how many seconds, the target is how many seconds?
