Doloto is a shorthand for "Download time Optimizer". The official page says it is especially useful for large, complex AJAX applications, because these applications contain a lot of JavaScript code. To put it simply, it works by stripping out the JavaScript code that was first used in the page, minimizing the amount of JavaScript that was loaded when the page was initialized, and then loading the other code in an asynchronous way.1. Doloto analyzes your application, it creates a local proxy to i

The 33rd lines of code shown in the figure are program code leaks, which are not difficult to find out.If we want to further evaluate the memory usage, we can look at the line chart of the allocations template. We can also see the memory usage of various variables at a certain time point. The heap (HEAP) memory usage in Area 4 is because the heap memory needs to be manually released, and the stack memory does not need to be

Not all are shown and hidden, but using viewstub is more troublesome. There is really a difference, it will involve th

CCleaner is a free system optimization and privacy protection tool. CCleaner's main use is to clear the garbage files that Windows system no longer uses to free up more hard disk space. Another big feature of it is to clear the user's internet record. CCleaner small size, fast speed, can be temporary folder, history, Recycle Bin, such as Garbage clean-up, and the registry can be scanned for garbage, clean.

image is not held. In order to test this fix, start the instrument again (with CMD in Xcode) and repeat the steps.Do not forget to end the memory warning in the simulation!Note: Make sure you exit from Xcode and rebuild instead of just clicking on the red button on the instrument to make sure you're using the latest code. This analysis should look like this: memory is severely degraded by memory warnings at this time.But there is still some memory overall growth, but not as much as it used to b

Android performance optimization: asynchronous image loading tool with dual cache (LruCache + SoftReference ), Previously, I used the LruCache algorithm to implement image caching in Guo Dashen's blog. here, I followed his ideas and wrote one myself. concurrentHashMap The following idea is that the LruCache class provided by the system is used as a level-1 cache, with a size of 1/8 of the running memory.

You are all the way to the carriage. is to get the ash report for the recent 15 minutes. 2. You are based on oldest ash sample available time and then enter, choosing the longest ash execution 3 that can be collected at the moment . You can choose oldest Ash sample available and latest Ash sample Time between available, then enter the duration, for example 30 for 30 mi

. You are all the way to the return, is to get the latest 15 minutes of ash report. 2. You are based on oldest ash sample available time and then enter, choosing the longest ash execution 3 that can be collected at the moment. You can choose the time between oldest Ash sample available and latest Ash sample available, and then enter the length, for example 30 for 30 minutes, whichever time you want to take the ash reportThe ash report can also be obtained directly by hand, for example, select Ou

Real time includes CPU times and waiting, switching, and so on, so it is generally larger than the CPU. Comparisons can determine if the time-consuming operation is within the CPU execution segment. C. The% of the above four indicators indicates the percentage of the function in total time. Easy to see the time ratio of a function. D. calls+recurcalls/total represents the number of external calls + recursion count/total number of times. You can see if the number of calls matches your expectat

unified require.config configuration placement file, relative BaseURL pathBecause the multi-page project needs multiple inbound files, this time will appear the same require config in a project configuration multiple times, in order to avoid this problem, you can put the same config of multiple inbound files into a JS file, unified configuration,And will use the Mainconfigfile parameter of the Build.js to redefine the module.Examples can be consulted: Https://github.com/requirejs/example-multip

Android Lint Tools is a static code tool that comes with Android Studio, Android Lint is a custom check rule specifically for Android, so you can check out many of the Android-specific code flaws. It is recommended that during the development process, it is a good time to regularly check the code for problems and to run lint before each test function module.Android Studio itself integrates Android Lint, right-click on any of the one by one folders in

spent on each step and the CPU and block Io, so that we can optimize the query statement more specifically. As you can see, because this is a full-table scan, the most time-consuming here is on sending data. In addition to this scenario, the following situations can also be time consuming:converting HEAP to MyISAM (when the query results are too large, put the results on disk),create TMP table (creating a temporary table, such as group storage Intermediate results),Copying to TMP table on disk
