OS: RAM difference between Ubuntu x86 (32 bit with physical address) and Ubuntu x64 (64 bit) OS: RAM atšķirība starp x86 Ubuntu (32 bitu ar fizisku adresi) un Ubuntu x64 (64 bitu)

The first ever version of Ubuntu I have installed on my computer was Hardy Heron 8.04 (x64/64 bit). Pirmais versija Ubuntu man ir uzstādīta uz mana datora bija 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. Kā laiks pagājis, un jauno versiju, šķiet, man ir modernizētas, lai jaunākā versija 8,10 Intrepid Ibex. 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. Kā web izstrādātājs, tas notiek dažreiz, lai palaistu pārāk daudz vienlaicīgu pieteikuma izskatīšanu laikā, kas rada lielu RAM patēriņš. Back then (still the x64 version) 2GB of ram was not enough, only Netbeans consumed 1GB of RAM and Firefox – about 800MB. Toreiz (joprojām x64 versija) 2GB RAM, nebija pietiekami, tikai NetBeans patērē 1GB RAM un Firefox - aptuveni 800MB. Sometimes my computer got frozen and hampered myself from doing my job without interruptions. Dažreiz manā datorā got iesaldēti un kavē sevi no šādas mans darbs bez pārtraukumiem. So I added another 2GB of RAM (totaling 4GB). Tāpēc es pievienoja vēl 2GB RAM (totaling 4GB). With that amount, my PC worked very well, better than ever (even though hibernating my PC was taking ages). Šī summa, mans PC strādā ļoti labi, labāk nekā jebkad (kaut gan ziemojošo datoru ir lietojis vecumu). 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 Diemžēl, bet uzlabojumus mundrs Jackalope, tas notika sadursmes laikā procesā, kas noved pie pilnīga zaudējuma informāciju par mana cietā diska (un jā man nebija backup mani dati ). ). The second times I've considered to install Jaunty Jackalope 9.04, but this time the 32 bit version. Otrās reizes es esmu uzskatāms instalēt mundrs Jackalope 9,04, bet šoreiz 32 bitu versiju. 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. Es biju ļoti pārsteigts pamanīt, ka, lai gan darbojas tajā pašā vairākām programmām (pie pašā laikā!) Tikai 75. daļu no RAM no summas RAM izmanto 64 bitu sistēma tika izmantots x86 versija. 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). Man bija vēl vairāk pārsteigts redzēt, ka, kamēr par 64 sistēmas Firefox bija stulbs paradums ēdot pārāk daudz RAM (~ 800MB labāko gadījumos), uz 32 bitu sistēmas, Firefox izmanto tikai 120MB RAM, kaut gan tas ir pilnīgi piekrauts ar smago Javascripted tīmekļa vietnes (Digg, Facebook vai 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). Tātad, kad jūs šaubas par to, vai instalēt Ubuntu x86 vai x64, paturiet prātā, ka x64 versija noārda savu RAM resursus. Bet, no manas pieredzes, x64 versija strādā daudz, daudz ātrāks par divkodolu procesori nekā x86 versija ( un ka ir vienīgā priekšrocība, es esmu šobrīd nav). 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. Paturiet arī prātā, ka, ja jums ir vairāk nekā 3GB instalēta jūsu datorā, jums ir jāuzstāda Physical Address Extension no Synaptic Package Manager, izraisīt, ja jums nav darīt, sistēma atpazīs tikai ~ 3.4GB RAM no kopējās summas RAM.
