To kick things off: why you even need to do this in the first place. Are you running out of memory? Is your CPU melting like butter under a hot sun? Do you have more cats than RAM slots? If any of these scenarios sound familiar, then it’s time to get serious and optimize that Jetson Linux!
Now, Time to get going with some tips for optimization. First off, the big one: memory management. You can start by running `free -m` in your terminal to see how much RAM you have available. If it looks like a desert wasteland out there, then we need to do something about that!
One way to free up some memory is to disable unnecessary services. To do this, run `sudo systemctl list-unit-files | grep -i disabled` and look for any units with the word “disabled” in them. If you see anything suspicious or unnecessary, then go ahead and disable it using `sudo systemctl disable
Another way to optimize memory is by reducing swap usage. To do this, run `sudo sysctl vm.swappiness=0` (this will prevent the kernel from swapping out data) and `sudo sysctl vm.vfs_cache_pressure=50` (which sets a threshold for when to start caching).
Now CPU optimization. If you have multiple cores, then it might be worth running your application on all of them using the `–cpu-affinity` flag in your script or command line. This will ensure that each core is working at maximum capacity and not wasting any cycles.
Another way to optimize CPU usage is by reducing interrupts. To do this, run `echo 0 > /proc/sys/kernel/realtime_idle` (this disables real-time scheduling) and `echo 1 > /proc/sys/kernel/sched_rt_period_us` (which sets the period for real-time tasks).
Finally, file system optimization. If you have a lot of data to store or read, then it might be worth using a faster file system like XFS instead of ext4. To do this, run `sudo mkfs -t xfs /dev/
With these tips, your Jetson Linux should be running like a well-oiled machine. Just remember to always test your application thoroughly after making any changes, and don’t forget to backup your data before making any major modifications.
