Various tests were conducted by varying the number of CPUs and RAM from 2 to 56GB and different I/O configurations (4k or 8k page size). This benchmark's 64 GB RAM machines had four physical CPUs with eight cores per CPU, 32 logical processors. The hardware and software configuration of each apparatus is summarized in the following table: These machines have Windows Server 2008 R2 installed with SQL Server 2012 Enterprise Edition. The benchmark consists of 23 warehouses distributed across 11 servers: 3 web servers, three application servers, five database servers, two report servers, and one login server. The TPC-E result is a transaction rate measured in transactions per minute (tpmC). The TPC-E standard defines a benchmark that measures performance using OLTP transactions. This article looks at the difference between RAM and Disk I/O in SQL Server by comparing the TPC-E benchmark data. But after a specific point, memory paging from the disk takes over and becomes slower. RAM is faster than a disk for small reads and writes. In a web hosting context, disk space (also known as disk storage or webspace) refers to the size of storage on a server available to host the content of your website. More rotations mean more time for your computer to access files, which slows down performance.Įvery device, application, and website needs somewhere to store its files. The more data you store, the faster your hard drive will need to rotate. It's measured in bytes (B), kilobytes (KB), megabytes (MB), or gigabytes (GB).Ī disk drive stores data by magnetizing areas on a spinning metal disk with electric currents and reads them with magnetic heads. This article will explain disk space and the two types of storage spaces: physical and virtual.ĭisk space is a term used to describe the amount of information stored on an electronic device. However, disk space is not the only type of storage space you can have on your computer. Disk space, or storage space or web space, is the total amount of storage on a web server where you store website's files and content.ĭisk space is a term used to describe the amount of data stored.
