PHP's JIT compiler can significantly improve performance in specific scenarios, but has limited impact on most web applications. 1. PHP's JIT accelerates CPU-intensive tasks such as mathematical calculations and complex algorithms by compiling frequently executed code into native machine code. 2. It relies on OPcache and uses DynASM to generate machine code at runtime, supporting multiple architectures and compilation modes. 3. There is almost no performance improvement for I/O-intensive applications such as Laravel or WordPress, because the bottleneck lies in database or network waiting rather than CPU. 4. To enable JIT, opcache.jit, opcache.jit_buffer_size and other parameters, and ensure OPcache

Adjusting the layout of Navicat workspace can significantly improve work efficiency. The key is to arrange panel and view locations based on common tasks such as querying databases, comparing patterns, or managing multiple connections. 1. Flexible adjustment of the panel status by dragging, double-clicking the title bar or using the "Auto Hide" button; 2. Customize the toolbar, add high-frequency functions (such as exporting results, data transmission), remove infrequently used items and sort them as needed; 3. Make good use of multi-labels and split-screen views, drag the tags to the edge of the window to achieve vertical or horizontal splitting, and reasonably allocate relevant and irrelevant content; 4. After completing layout optimization, you can save the configuration through "Tools > Options > Workspace" to facilitate restoring the default or resetting the chaotic interface. Although the personalized settings are small, they can greatly improve the smoothness of operation.

The method of checking database size varies according to the database type. The mainstream practices are as follows: 1. MySQL obtains the total database size by querying information_schema, or use graphical tools to view it; 2. PostgreSQL provides the pg_database_size and pg_size_pretty functions to display the size and formatted output of the specified database; 3. SQLServer uses the sp_spaceused stored procedure or view disk usage through SSMS; in addition, you need to pay attention to permissions, remote access restrictions and recommended to monitor the database growth trend regularly.

64-bit JVM supports larger heap memory and wider memory addressing, but requires weighing memory overhead and performance. The 1.64-bit JVM breaks through the 32-bit limit and can support dozens to hundreds of GB of heap space, suitable for big data and high object retention scenarios. 2. Object reference increases from 4 bytes to 8 bytes, increasing memory usage, but the compressedoops enabled by default (when the heap is less than 32GB) compresses the reference to a 32-bit offset, reducing memory consumption and improving cache efficiency. 3. If the large heap causes the GC pause time to be extended, you should use garbage collectors suitable for the large heap such as G1GC, ZGC or Shenandoah, and reasonably set the heap size through -Xms/-Xmx, select the appropriate GC strategy, and monitor the GC log to optimize performance. 4.
