Tool has been confirmed to work with AIMS Desktop media. Tool at which makes writing USB disks from Windows really easy and that If you’re using Windows and don’t have access to a Linux device, you can download the Rufus USB The command directly to a raw USB device. If you’re familiar with the dd command, you can use that from your Linux or macOS system to write On that USB disk, you should move it to a safer location before writing the installer to disk. Preparing it as an installationĭisk for AIMS desktop will overwrite all the data that’s on there, so if you have important files You will need a USB disk that is at least 4GB large. It can be installed alongsideĪn existing system such as Microsoft Windows, Apple macOS, BSD or another GNU/Linux system. PreparationĪIMS Desktop installs a new operating system to your computer. You might want to download it on a broadband connection instead. I just need to test it out for a couple days to see if it was all in my head or not.AIMS Desktop is a large download (over 3GB), if you’re reading this from a mobile connection, The only thing I do not understand is: How does vm.vfs_cache_pressure being 50 as opposed to 1 maintain a reasonable sense of perceived performance while still copying over the large files from one directory to another? I honestly feel that that change of vm.vfs_cache_pressure from 1 to 50 had a huge impact. o-fix-that) explains very well what I was experiencing especially on my old laptop (before I replaced it for this one). Why do you suggest a vm.swappiness of 20? I have 3GB RAM and it's always far from being completely used. How is this incorrect? Also, I think that having a vm.swappiness of 0 and vm.vfs_cache_pressure of 50 actually improved things dramatically but it could just be in my head. I've read everywhere that if you have a lot of RAM and only use swap as a emergency backup that that is what you should have. I do want my swap to only be touched if I run out of RAM which is why I chose a vm.swappiness=0. It has to be "awake" because it runs and downloads stuff usually. If you really do leave you PC unattended and idle for extended periods and it supports suspend then why not use that? My desktop and laptops suspend to RAM instantly (OK about a second) and resume reliably. I do a lot of big file transfers but I have my desktop set up so most big files do not reside on the same physical disk as the OS and I always did the same in Windows for the same reasons, and I offload p2p activity and other long downloads onto other disks and other computers, again for the same reasons. Make sure you use relatime or even better noatime in fstab, that should help quite a lot. There's a whole discussion in that thread, the above is a summary.Īnyway if your disk is busy writing then performance suffers, there's no escaping it. IMHO, the VM on a desktop system really should be optimised to have the best interactive behaviour, meaning decent latency when switching applications." Andrew Morton humorously replied, "I'm gonna stick my fingers in my ears and sing 'la la la' until people tell me 'I set swappiness to zero and it didn't do what I wanted it to do'." Rik van Riel explains, "Making the user have very bad interactivity for the first minute or so is a Bad Thing, even if the computer did run more efficiently while the user wasn't around to notice. The other side of the argument is that if "BloatyApp" is swapped out too agressively, when the user returns to use it he has to wait for it to swap back in and thus detects a noticable delay. Get it out on the disk, use the memory for something useful." You really don't want hundreds of megabytes of BloatyApp's untouched memory floating about in the machine. "My point is that decreasing the tendency of the kernel to swap stuff out is wrong. 2.6 kernel maintainer Andrew Morton noted that on his own desktop machines he sets swapiness to 100, further explaining: The higher a number set here, the more the system will swap. To tune, simply echo a value from 0 to 100 onto /proc/sys/vm/swappiness. Fortunately a run-time tunable is available through the proc interface for anyone needing to adapt kernel behavior to their own requirements. A number of Linux kernel developers recently debated "swapiness" at length on the lkml, exploring when an application should or should not be swapped out, versus reclaiming memory from the cache.
