Choice of language is less important for more recent contests, since problem setters have made an effort to level the playing field (e.g., by testing Java solutions to ensure that the time limit is sufficient).
If your application server hasJMX console, Thread pools can be monitored via the MBeans, but it can be a painful process. You can also write your own Java program (JMX client) to connect and retrieve values from the Mbeans. Easy way is to install a commercial APM tool. Some Application...
No wonder java IO is so slow! Labels:bloopers,java,VirtualAnt posted by Prashant Deva, 2:19 AM 2 Comments: wow!!! I had to open the source just to look. At least its only in the setError method so, its not being called in a loop. ...
If in the past few months you’ve noticed that your web pages are loading slowly, it’s likely that your Mac is in need of some maintenance. In this article, you will learn why your browser is so slow, how to solve slow browser issues, as well as how to speed up Chrome, Safari, ...
There's a reason Java maintained popularity for such a long period of time. The language's conservative, slow and steady approach is the key to its success.
I quickly searched through the code for anything suspicious, but I could not find anything — it seems to be very clearly O(n^2), with n at most 5000... but it still takes far too long: running it on my computer it seemed to take more than 1 second for the loop where I simply...
()is pretty fast outside of Android, despite the method’s slow implementation in Android. Consequently, many Android apps are affected by this issue because many Android developers come from the Java world and want to use familiar libraries in their Android apps (e.g., Joda-Time instead of...
(You know… slow relative to what?) To correct this, I will develop, in this article, not just one useful equivalency for JavaScript performance–but three of them. So I’m not only going to argue the “traditional hymns” of “wa wa JS is slow for arbitrary case”, but I’m going...
Does ArkTS provide a method similar to System.arraycopy in Java? Should I change the file name extension of all ArkTS files to .ets? Where is the .abc file generated after the build? What are the differences between ArkTS and TS files? How do I implement string encoding and deco...
