![]() The following screenshots show the CPU usage before and after optimization while searching a very large file for a regular expression. To overcome this situation, I optimized the code so that v22.5 will dynamically manage thread load balancing. Nevertheless, the existence of P-Cores and E-Cores could exacerbate the situation. Just for clarification, thread speed could fluctuate even without E-Cores and P-Cores for instance, if a thread is interrupted by a background app or system process, the thread will become slower than other threads. If a P-Core thread runs faster than an E-Core thread, P-Core threads finish their task earlier than E-Core threads and need to wait for E-Core threads to finish their task. All previous versions of EmEditor assumed that all threads run at the same speed. This new architecture is interesting because a P-Core runs faster than an E-Core. Since the 12th Gen Core processors, Intel has introduced a hybrid architecture that combines P-Cores for performance and E-Cores for efficiency. Improved the speeds of adjusting CSV separator positions, CSV syntax check, switching to the normal mode from a CSV mode, and various conversion and sort commands while working on a very large file.- I recently bought a PC with a 13th Gen Intel Core i7-13700.Updated CSS HTML Validator Lite to v21.0.Added to ability to filter history in CommitList.The CommitList plug-in can now call the pull, push, and fetch commands.Added the \V expression to the Replacement Expression Syntax and allowed you to use the V8 JavaScript engine for replacement expressions.The new version shows a a message box indicating a low memory situation as well as a clickable URL to explain how to increase the virtual memory if the situation happens.Improved the reliability and robustness especially when dealing with very large files in low memory situations.The new version allows CSV detections work even if embedded newlines exist.Previous versions check CSV syntax always in the foreground. The new version may check CSV syntax in the background, which allows you to view the file without waiting for the syntax check finished.The new version initiates a CSV detection in the beginning of opening a very large file, which allows you to view the file in a CSV mode without waiting for the entire file loaded. ![]()
