as said before, i want some SRAM module for my PC. nice that you can get some triple channel DDR3 that gives you a max bandwidth of more than 25 Gigabyte per sec, but what if you need a few bytes here and there? LATENCY is the killer. or let’s say you run some virtualization software – with hundreds or thousands of context switches per sec. everytime your cache content becomes kind’a obsolete!<\/p>\n
i don’t know the actual numbers of how much time gets lost – some cores can work on some other tasks while waiting for data, but it ain’t good. we see more SSDs, more RAM, more cores but what feeds a truly random access best? SRAM!<\/p>\n
PLEASE PLEASE PLEASE – just a gig or two<\/p>\n
of course some new software developments like randomization to prevent hacker attacks (eg spraying) make this approach only limited as for the speedup, but we need to differentiate between RAM data: you buy a speedy SSD or \u00a015k disk if you expect lots of random access, and a few TB with 5-7k if you need space. \u00a0so why not do the same with RAM?<\/p>\n
virtualization is another beast – frequent context changes NEED fast RAM for the heaps, registers etc but may not move much data …<\/p>\n","protected":false},"excerpt":{"rendered":"
