OS: RAM difference between Ubuntu x86 (32 bit with physical address) and Ubuntu x64 (64 bit) 操作系统：内存与Ubuntu的x86（32位的物理地址）和Ubuntu的x64（64位差异）

The first ever version of Ubuntu I have installed on my computer was Hardy Heron 8.04 (x64/64 bit).有史以来第一次版本的Ubuntu，我在我的计算机上安装的是吃苦耐劳的Heron 8.04（x64/64位）。 As time passed and new versions appeared, I have upgraded to the latest version of Intrepid Ibex 8.10.随着时间的推移和新的版本出现，我已升级到8.10的无畏北山羊的最新版本。 As a web developer, It happens sometimes to run an excessive number of simultaneous applications at a time, which leads to a huge RAM consumption.作为Web开发者，有时它发生的运行一次同步申请，人数过多而导致巨大的内存消耗。 Back then (still the x64 version) 2GB of ram was not enough, only Netbeans consumed 1GB of RAM and Firefox – about 800MB.当时（仍是x64版本），2GB的内存是不够的，只有Netbeans的消耗大约800MB的内存和1GB的火狐- 。 Sometimes my computer got frozen and hampered myself from doing my job without interruptions.有时，我的电脑被冻结，阻碍了做我的工作没有中断自己。 So I added another 2GB of RAM (totaling 4GB).因此，我增加了一个2GB的内存（共计4GB的）。 With that amount, my PC worked very well, better than ever (even though hibernating my PC was taking ages).这一数额，我的电脑工作非常出色，比以往更好地（即使冬眠我的电脑正在岁）。 Unfortunately, while upgrading to Jaunty Jackalope, it happened a crash during the process, which lead to a total loss of information on my hard-disk (and yes I didn't backup my data不幸的是，在升级到jaunty中Jackalope，但在此过程中发生碰撞，从而导致我的硬盘（当然我没有备份到的信息全部损失我的资料 
). ）。 The second times I've considered to install Jaunty Jackalope 9.04, but this time the 32 bit version.第二次，我认为安装jaunty中Jackalope 9.04，但是这一次的32位版本。 I was very surprised to notice that while running the same number of programs (at the same time!), only the 75th part of RAM from the amount of RAM used on the 64 bit system was used on the x86 version.我很惊讶地看到，在运行的程序相同的号码（在同一时间！），只有内存从内存在64位系统上的使用量75部分是在x86版本中使用。 I was even more surprised to see that while on the 64 system Firefox had the stupid habit of eating too much RAM (~800MB in best cases), on the 32 bit system, Firefox is using only 120MB of RAM, even though it's fully loaded with heavy Javascripted websites (Digg, Facebook or Mashable).我更惊讶地看到，在64系统的Firefox被吃太多愚蠢的习惯内存（〜800MB的，在最好的情况下），在32位系统上，Firefox是只使用120MB的内存，即使它的满载重型（Digg，Facebook或Mashable）Javascripted网站。 So, when you doubt of whether to install Ubuntu x86 or x64, keep in mind that the x64 version will deplete your RAM resources. But , from my experience, the x64 version works much, much faster on dual core processors than the x86 version (and that's the only advantage I am currently missing).所以，当你怀疑是否安装Ubuntu x86或x64，请记住，在x64版本将消耗你的内存资源。 但从我的经验，x64版本，作品不多，就快得多比x86版本的双核心处理器（而这唯一的优势，目前我丢失）。 Also keep in mind that if you have more than 3GB installed in your PC, you will have to install the Physical Address extension from the Synaptic Package Manager, cause if you don't do it, the system will recognize only ~3.4GB of RAM from the total amount of RAM.同时请记住，如果你有超过3GB的安装在电脑的，你必须安装从Synaptic后，引起物理地址扩展，如果你不这样做，系统将只承认〜3.4GB的内存从RAM的总量。
