OS: RAM difference between Ubuntu x86 (32 bit with physical address) and Ubuntu x64 (64 bit) OS: RAM forskellen mellem Ubuntu x86 (32 bit med fysisk adresse) og Ubuntu x64 (64 bit)

The first ever version of Ubuntu I have installed on my computer was Hardy Heron 8.04 (x64/64 bit). Den allerførste version af Ubuntu har jeg installeret på min computer var Hardy Heron 8.04 (x64/64 bit). As time passed and new versions appeared, I have upgraded to the latest version of Intrepid Ibex 8.10. Som tiden gik, og nye versioner syntes, jeg har opgraderet til den nyeste version af Intrepid Ibex 8.10. 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. Som web-udvikler, sker det ofte, at køre et uforholdsmæssigt stort antal samtidige ansøgninger på et tidspunkt, hvilket fører til en enorm RAM forbrug. Back then (still the x64 version) 2GB of ram was not enough, only Netbeans consumed 1GB of RAM and Firefox – about 800MB. Dengang (stadig x64 version) 2 GB RAM var ikke nok, kun Netbeans forbruges 1 GB RAM og Firefox - omkring 800MB. Sometimes my computer got frozen and hampered myself from doing my job without interruptions. Sommetider min computer fik frosset og hæmmede mig i at gøre mit arbejde uden afbrydelser. So I added another 2GB of RAM (totaling 4GB). Så jeg tilføjede en anden 2 GB RAM (i alt 4 GB). With that amount, my PC worked very well, better than ever (even though hibernating my PC was taking ages). Med dette beløb, arbejdede min PC meget godt, bedre end nogensinde (selvom overvintrende min PC fandt aldre). 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 Desværre, mens en opgradering til Jaunty Jackalope, det skete et styrt på den proces, der fører til et samlet tab af information på min harddisk (og ja jeg har ikke sikkerhedskopiere mine data ). ). The second times I've considered to install Jaunty Jackalope 9.04, but this time the 32 bit version. Den anden gange jeg har overvejet at installere Jaunty Jackalope 9,04, men denne gang den 32 bit version. 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. Jeg var meget overrasket over at konstatere, at mens den kører det samme antal programmer (på samme tid!), Kun den 75. del af RAM fra mængden af RAM, der anvendes på 64 bit system blev brugt på x86-versionen. 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). Jeg blev endnu mere overrasket over at se, at selv om den 64-systemet Firefox havde den dumme vane at spise for meget RAM (~ 800MB i bedste fald), om de 32 bit system, er Firefox bruger kun 120MB RAM, selvom den er fuldt lastet med tunge Javascripted hjemmesider (Digg, Facebook eller Mashable). 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). Så når du tvivl om at installere Ubuntu x86 eller x64, huske på, at den x64-versionen vil nedbryder din RAM ressourcer. Men fra min erfaring, at x64-versionen fungerer meget, meget hurtigere på dual core processorer end x86-versionen ( og det er den eneste fordel, jeg er i øjeblikket mangler). 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. Også huske på, at hvis du har mere end 3GB installeret på din pc, skal du installere Physical Address Extension fra Synaptic Package Manager, for hvis du ikke gør det, vil systemet genkende kun ~ 3.4GB RAM fra den samlede mængde RAM.
