Just one quick point about running a VM on shared hardware. If there are multiple VMs, you can't be sure what's going to happen to your access to I/O. If the other VMs are idle, no problem. If they're using RAM, no problem...but if they're reading to or writing from disk...that can be a problem. Some applications are inherently (or likely to be) heavily disk-bound more than others. Databases are pretty much first on the list of disk-bound apps. A Web server can spit out zillions of pages, largely from RAM and without a lot of CPU. For a database, writing to disk is important. When you're on a machine that's got a few other VMs running it can make a huge difference what they're doing.
So, if you talk to a provider about performance on a mutli-VM server, make sure they're talking about databases (and the like) not Web servers (and the like.) ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
