VPS hosting select 32bit or 64bit?
Before I gave a briefing on VPS purchase of related articles, said today that the following VPS select 32-bit or 64-bit.
32-bit and 64-bit pre-existence of present and future
Currently widely used CPU architectures are x86 and x86_64. Where x86 is the early introduction of Intel’s 32-bit CPU architecture, previously used by the vast majority of our desktop CPU is x86 architecture, including some of AMD’s CPU.
x86_64 is designed in recent years, AMD introduced 64-bit CPU architecture, x86_64 architecture has just launched when they were called AMD64. x86_64-compatible 32-bit x86 architecture is a very successful 64-bit CPU architectures. Intel in AMD after the launch of x86_64, also launched its own x86_64 architecture CPU, but Intel called x86_64 for Intel64, EM64T.
32-bit and 64-bit systems the advantages and disadvantages
64-bit system can access more than 4GB of memory address space of the large, compared with 32-bit systems can only access 4GB of memory address.
64-bit performance of the system have some improvements, because there are 16 general-purpose CPU registers, compared with 32-bit systems only 8.
Through the use of optimized x64-64 CPU instruction, performance upgrade.
Look at the web application tests show that the same 64-bit systems than 32-bit systems to consume at least 60% or more of memory, which implies the need to pay more costs.
Performance loss, because the 64-bit is 8 bytes, compared with 32-bit system, only 4 bytes.
As x86_64 compatible with x86, 32 bit Windows and Linux operating systems can be a very good run on the CPU on x86_64. x86-CPU can only run 32-bit operating system, and x86_64 only the CPU can run 64-bit operating system, you can also run 32-bit operating system.
Linux operating system, Linux kernel and applications is divided into two parts. x86_64 CPU can run 64-bit Linux kernel, and 32-bit applications, while the 32-bit line Linux kernel can not run 64-bit programs.
See Linux kernel is 32-bit or 64-bit, you can run the command: uname-a, see the application run the command: file / usr / bin / *.
I had used DiaHosting, Rashost, Photonvps, Linode, Rapidxen and a number of 32 bit and 64 VPS, experience also shows that, unless you have a special needs 64-bit, otherwise it is recommended that the use of low-cost, high speed 32-bit System
