I tried an in-memory Linux distro and I was shocked by how fast it was.  Is there is a way to always cache in memory some (user specified) software like the file explorer so that you can benefit of that speed without having to preload the whole system in the memory (unfeasible if it's your main desktop because there would be not enough memory)

My PC has 8 Gb of ram. Is there any way to make ubuntu use most of it? I mean rarely drop caches and keep once opened programms in ram longer, preload apps on boot, etc.

I am a student at Case Western Reserve University, and the bandwidth from the Ubuntu servers to my location is often horrendously bad (on the order of a few hundred bytes per second). Myself and a few friends would like to be able to download the packages once, and have them cached for the rest of our Ubuntu installations on campus. To do that, we would either need to setup our own APT repositories, or setup some form of caching (squid?) server at which we could point our systems.  Is setting up such a mirror a difficult process? How would one accomplish it?

What is the most stable and easiest way to get readable access of linux partitions in windows?   All software and drivers I´ve found seem to have been dead/inactive for at least 4 years.  Native access is a plus.  Os: Windows 8.1

When I scanned my $HOME directory with baobab (Disk Usage Analyzer), I found that ~/.cache is consuming about half a GB.  I also tried to restart and again check size but no difference.  So, I am planning to rm -rf ~/.cache. Let me know Is it safe to clear ~/.cache?

If I copy a large amount of data from on drive to another (physical) drive my whole system is running slow.  I am using Windows 7 64bit version on an Intel Core 2 Duo 3 GHz.  This is the situation:   Very fast copying between two SATA disks.  Resource Monitor shows 80MB/s read, 70MB/s writes and 150MB/s total The total CPU load is about 3% There is plenty (>2GB) of free physical RAM left All partitions have enough (>10gb, >10%) of free space left and show low fragmentation Anti-Virus software is not active   This is the problem: No matter what I want to do while copying, it takes forever. Even tasks that do not need a lot of disk access (as they should work from RAM only), are extremely slow. The moment I stop the copying process, all the unfinished tasks finish at once. For example trying to open a new browser windows or explorer window will not work. If the copying is stopped 5 explorer windows popup at once.  My question is: why? What resource is exhausted, if CPU and memory are idle? And what part of my computer hardware I need to upgrade to get better behavior? Also read Psycogeek's comment for further questions in this direction.  If your answer is, that everything needs HDD Access, which is blocked by such an activity, then my question is: Is there a way to copy something on your system without rendering it unusable until its done? (which can be hours, if >500g have to be copied).

I am doing experiments with few Linux kernels, also I want to keep all the kernels on my system; I don't want then to be removed automatically. how do I achieve that?  (NOTE: I have mounted /boot on separate 4GB partition so space is not an issue)

My motherboard (HP Pavilion s3000y) only supports 2GB of RAM max. Which means that I can only allocate 1GB for running VMs, and applications that use a lot of RAM are slow (such as games and Visual Studio).    Is it possible to use a storage disk such as a USB drive as RAM?    Or if not, can VirtualBox use a drive as RAM for VMs?

I've been researching memory mapped files for a project and would appreciate any thoughts from people who have either used them before, or decided against using them, and why?  In particular, I am concerned about the following, in order of importance:   concurrency random access performance ease of use portability

I know that Cache is working memory that is faster than RAM, but in my system there is only 3MB of it, and most programs will require more working memory than 3MB.  So that makes me question what cache is used for in my system.

I am a Windows user and coming from Windows with all the indexing and eternal wait times when searching for files, I find it surprising how fast does locate work or the autocompletion (that I know) work in linux.  Is there any indexing being done in the background or how is this achieved? I still have a pretty clean installation, so maybe this goes bad with time, but in Windows the moment you want to search on a folder which is not indexed you have to wait for some seconds.

Why is defragmenting unnecessary in Ubuntu?

I thought that Windows 8 was supposed to be better with memory than Windows 7. So far, that is not my experience.  When I boot up my brand new laptop (Samsung NP550P5C-S03CA Intel Core i5 3210M 8GB 1TB ) , the Task Manager Performance tab tells me that I have:  8.0 Gb of DDR3 available  of this:  3.7GB is in use, leaving 4.2GB available  3.5/25.9 GB is committed and 1.4GB is cached.  162Mb paged pool, 2.4GB non-paged.  I then go to the Details tab, and I add up the Memory used by all the processes. It comes to about 300Mb. That is 0.3GB.  So what is using up the other 3.4GB of memory???  I then load up a bunch of programs that I use concurrently - notably Firefox (with about 30 tabs), Chrome, Thunderbird, Notepad++, Filezilla and my memory consumption goes up to 4.4GB. That seems about right.  I then work on it for a number of days, hibernating in-between, and I start to get notices that I am running low of memory. The performance tab says I am using 90% or more of my memory. The committed has gone up to 31GB. But if I add up the memory usage listed in the Details tab, it comes to only about 1800MB (I notice that Firefox has gone up to about 1300MB)  So, again, where has all my memory gone?  If I then close all the programs, it doesn't help. The details tab shows little running, yet the Performance tab shows I am still out of memory?  What is using up all my memory?  The only thing that clears it, is to do a restart. Which brings us back to the top of the loop, with the same initial question - what is using up over 4GB of my memory?  I never had these problems with windows 7.  As a sidenote, Win 8 also seems to be very unstable. Frequently getting programs not responding and crashing, including Windows Explorer, which seems to have to reload itself frequently.  Oh, and my wifi connection keeps dying and then I have to run the troubleshooter to get it all running again (my wife has that same problem on her brand new Acer).  So, what gives? How do I get my new laptop to work as fast as my 4 year old Sony Vaio with Win 7 and lower specs?  Anyone got any ideas? Or is this normal for windows 8?

Is there any way to set a system wide memory limit a process can use in Windows XP? I have a couple of unstable apps which do work ok for most of the time but can hit a bug which results in eating whole memory in a matter of seconds (or at least I suppose that's it). This results in a hard reset as Windows becomes totally unresponsive and I lose my work.  I would like to be able to do something like the /etc/limits on Linux - setting M90, for instance (to set 90% max memory for a single user to allocate). So the system gets the remaining 10% no matter what.

I'm looking for a linux alternative to . I would like to know what is taking up space on my hard drives.  A program that works on console and doesn't require a UI is preferred .

I've been building my own Linux distro, and I've stripped the binaries, etc. The system won't use GCC or development tools, as it will be a Chrome kiosk, so it would greatly help if I could strip down the system...  I was wondering, is there a way that I can delete all of the unused system files (like binaries, etc.) by watching what files/libraries are used during runtime? Maybe another method is preferred, but is there a way to accomplish something like this?

Does it stil make much difference, now that we have much faster and larger HDDs? Generally I find if disk performance is getting too slow, it's probably because of too little free space, and the solution is to buy a new HDD.

My relatively fresh Ubuntu 19.10 on a top notebook is running flawlessly, but some applications are really slow to start. For now it's keepassX, filezilla, deadbeef. Both takes about 30 seconds to show it's window, but after that both are blazing fast as others. May be someone can help me to find a solution?
