It also depends on the virtual server platform you are using.André van de Graafhttp://www.blogger.com/profile/07230010757193182052noreply@blogger.comtag:blogger.com,1999:blog-8930349235661427759.post-60120766263105589422008-11-25T23:01:00.000+01:002008-11-25T23:01:00.000+01:00What is virtualization?Aad 't Harthttp://www.blogger.com/profile/07566387683675598847noreply@blogger.comtag:blogger.com,1999:blog-8930349235661427759.post-16266433528970900372008-11-25T22:48:00.000+01:002008-11-25T22:48:00.000+01:00Andre, good article. Someone wrote to me recently "On the use of virtual- or physical database servers we recommend using physical database servers, because the disk I/O performance is much better compared to virtual database servers. Disk I/O performance might drop up to 30% when using virtual database servers."<BR/><BR/>Any comment on that?Ronald Voetshttp://www.blogger.com/profile/01899266490150816323noreply@blogger.com
