IBM mainframes are sold, leased, and maintained on the basis of capacity. The machines are designed to run well at 99% usage, even though the desktop world is likely to view this as 'having no headroom.' That 'headroom' costs a lot of money that leasers would rather not pay for unless it's really needed But when the difference between 24 GB and 16 GB of RAM (at least on expandable machines) is $50-$75, the wasted memory is of no great concern. It is possible to design algorithms that use memory to save CPU cycles, and it is possible to design algorithms that use CPU cycles to save memory. The point I was trying to make is that some individual processes take up memory for a speed advantage, when there's enough to go around. Lab Tested: The ramifications of additional memory on a Mac. How much more RAM do you actually need? Macworld Lab ran benchmarks on a couple of Macs at different RAM configurations and analyzed. ![]() Because I have enough memory, I like this behavior. Because others don't, they're more likely to extol the genius of compressed memory. Windows 10 disc driver for mac. Totally new here - I appreciate that this thread is talking about ram as this topic is not everywhere. It's not about budget it's about how much ram a person really needs for smooth performance 8G vs 16G. ![]() Click to expand. I am going to buy a macbook, and I know that since I can only afford one laptop (not a desktop +laptop), I am going to need one solution fits all. I already decided to get the 2015 macbook pro 13', 2.9Ghz, 512GB, the only thing not sure it's 8G or 16G ram. My use: • OSX + VMware Windows 10 (really love to have smooth performance when switch between them) • web browsing 30+ tabs • word + excel in VMware Windows 10 (excel sometimes may be 50,000 - 100,000 rows data. Wii u emulator dolphin. File size about 16MB) • final Cut pro/ photoshop - not now, but will be using them sometimes, I will start learning them and would love to have smooth performance using them) • I do blogging/ website/ and going into mobile app business (xcode/ eclipse) • all the above remains open, but I will only do one task at a time, and will switch back and forth between them. • plan to use about 2 years • currently using thinkpad i5, 500 HDD, 16G ram, so far is smooth and no problem at all (in terms of performance, but not ok with windows OS). Just wanna switch to completely mac as windows is always weird. I would love to hear your opinions! Click to expand.Really? In my experience, it's somewhat difficult to use more than 8 GB of RAM (except cache, but that rarely yields substantial performance improvements.) It's extremely difficult to use more than 16 GB. Eventually, the kernel runs out of things to cache. VMs and photoshop, neither of which I use, tend to grab very large amounts of memory at the outset-- so if you use those programs, the decision to upgrade RAM should be trivial. Best torrent site for mac software. Most other programs are less aggressive in demanding memory. But, it's quite easy for me to use more than two cores. The compiler, for instance, is trivially configured to compile 4 source files at once. For something a little more exotic, my copy of Abby Finereader launches four FineExec processes, which can easily peg my CPU. Now, I don't have a portable machine, and have enough screenspace to work on several applications at once. On the other hand, Apple does use the 'race to sleep paradigm'-- the sooner the task at hand is completed, the sooner the machine can sleep.
