I have been using Xdebug-based PHP for performance analysis. it is enough for the local development environment. However, if it is an online environment, xdebug consumes a lot and the configuration is not flexible enough, therefore, xhprof is recommended for tracking and analyzing PHP performance in the online environment. I. Preface Record the useful items and facilitate future queries. this time, record the installation and use of xhprof; Xhprof is

AWStats Introduction AWStats is a fast-growing perl-based web log analysis tool on Sourcefroge. Compared with other tools, the advantage is that 1. User-friendly. You can directly call the corresponding language interface based on your browser (Chinese is supported ); 2. It is based on perl and can effectively solve cross-platform problems. 3. High Efficiency: a website with millions of daily visits can wit

Previously, a device file collection tool was developed using Java Swing. Supports multiple devices to be collected at the same time, using one thread per device. At the same time collect more than one device information, found that the CPU occupancy rate actually reached 97%, and high. Obviously, such performance is intolerable.We know that with the tools JVISUALVM the JDK, you can see the execution of each thread, but it is impossible to analyze the

everybody share under oneself to several big search engines outside the chain Inquiry tool observation analysis some experience. 　Why should we observe the chain of inquiry outside? Said the outside chain is an important factor in the rankings, in fact, the chain mainly from the number and quality of two aspects of the ranking. The role of the chain is equivalent to the interpersonal network, for exampl

That is, the size of the bubble chart meaning, divided into two kinds, area or width, the calculated units are pixels.The principle is to set the bubble size to 50, the maximum bubble radius in the entire bubble chart is 50 pixels, and then depending on the size of the selection, such as selecting the bubble area , the size of the other bubbles is adjusted according to the area of the bubble.

it is not omnipotent, there are two problems:1.XPath Helper automatically extracts the XPath from the root path, which almost inevitably lead to XPath too long, not conducive to maintenance;2. When extracting the list data for a loop, the XPath Helper is using the subscript to extract each piece of data separately from the list, which is not suitable for batch processing of the program, or the need to manually modify some similar to the * tag.However, a reasonable use of XPath, or can save us a

Occasionally found in the code there are some low-level errors, such as the copy memory out of bounds or the variable is not initialized to call, etc., resulting in the debug version is available but release version of abnormal phenomena, also inconvenient debugging.
