![]() Now, lets show you a demonstration of multiple codes that can heavily defect your memory usage. You may ask, Why will this use a lot of data? Now the main reason is that the script has to check EVERY time if the part is there and thus, it uses data. Now also a common mistake I see some do is parent a part before the properties are set. Only use loops when you cannot do an alternative script. ![]() Too much loops in your script is also a common reason since it runs data MANY times on the memory. Too much tools in starter pack will need to be replicated to the backpack and thus, using a lot of memory since your replicating data. Exploiters can also be the reason since their exploits run a LOT of data. Too much parts also will be the root problem since each part has data for it’s properties, appearance, mesh and etc. Too much scripts will run on the memory and start producing too much data on the memory and thus, using too much memory. Scripts contain data on their source(the script and what it runs), name and class name and every property. Too much scripts can use too much data/memory. When this happens, it’ll collect up and eventually, this will flatten connections between the server and the client because of the amount of garbage getting perceived by the client. When this happens, the memory won’t be able to handle the excess data and hence, it’s referred to as “garbage”. Memory usage is when a script runs too much data. Luckily, there is a garbage collector but some data won’t be collected. For example, a high MB amount such as 32 is considered as a lot of garbage. Hopefully, this quick tip helps you clear your system swap memory if you ever find yourself in need of just such a fix.Memory usage is determined by the status of your memory. (use free -m to see the amount of swap used/available decrease over time) Here are all of the commands you'll need! Check space: # free -m ![]() This clears the swap memory cache and re-enables it. Once you power it off, you can wait an arbitrary amount of time (30 sec or so) to give the operation time to complete, then power the swap back on. An easy way to do this is to run 'free -m' to see what is being used in swap and in RAM. It also means that you need to be sure you have the RAM to support this operation. This moves all data from swap memory back into RAM. To clear the swap memory on your system, you simply need to cycle off the swap. For the first time in your terminal life, things are going to be easy here. Easy day. Now that you understand the underlying parameters that control the swap behavior on our system, you're ready to learn how to clear that memory, should the situation arise. To verify the value that you set, simply cat the swappiness file that you looked at earlier to find out the original value. You can check your current swappiness setting by running the following command: $ cat /proc/sys/vm/swappiness If you wanted to change up the swappiness of your system, the procedure is very straight-forward. A value of zero causes no swapping at all to occur, so if you want to minimize swapping to its lowest possible value without turning it off, you should set it to at least one. Small values cause little swapping to occur, whereas high values can cause very aggressive swapping. The default value for swappiness is 60 however, you can manually set it anywhere between 0-100. Swappiness refers to the kernel parameter responsible for how much and how often that the system moves data from RAM to swap memory. So now that you know the lingo, you're ready to explore what it means. The culprit here is the ‘swappiness’ of the system. ![]() Occasionally, a system uses a high percentage of swap memory even when there is RAM available for use. This article is a discussion about this situation and the solution required. If that is the situation that you find yourself in, you’ve come to the right place. However, there is a niche situation that can cause an administrator to need to clear the system swap manually. Most enterprise environments have swap built into the systems, and these memory caches are not manipulated unless there is an apparent lack of memory available or if a server crashes due to the OOM killer (out of memory) error. Swap memory is usually a "set it and forget it" type of affair.
