Monitoring Resource Usage of cxImage in Debian
To monitor the CPU and memory usage of applications using cxImage in Debian, you can use system monitoring tools like top, htop, or glances. These tools provide real-time insights into process-level resource consumption—for example, running top in the terminal will display a list of processes with their respective CPU (%) and memory (RAM) usage; you can identify cxImage-related processes by their command names or executable paths. For more detailed memory analysis (including shared memory), smem is a useful alternative, while iotop helps track disk I/O usage, which is particularly relevant for image-heavy operations.

Optimizing Memory Usage for cxImage in Debian
If cxImage applications consume excessive memory, consider the following optimizations:

• Clear Temporary Files: Use lsblk and df -h to check disk space, then remove unnecessary files in /tmp or old logs to free up memory.
• Adjust Kernel Parameters: Modify the vm.swappiness value in /etc/sysctl.conf (e.g., set it to 10) to reduce the kernel’s tendency to swap memory to disk, which can improve performance for memory-intensive tasks.
• Diagnose Memory Leaks: Tools like Valgrind can help identify memory leaks in your application code—run your program with Valgrind to detect unreleased memory blocks and fix them.

Installing cxImage in Debian
While not directly related to resource monitoring, proper installation ensures baseline performance. You can install cxImage via APT:

sudo apt update
sudo apt install cximage

Or compile from source: download the cxImage tarball, extract it, and run ./configure && make && sudo make install. Note that cxImage depends on libraries like libpng, libjpeg, and libtiff—install them using sudo apt install libpng-dev libjpeg-dev libtiff-dev libgif-dev before compilation.
