Page History

This section gives some very rough guidelines for determining whether your VIVO is performing similarly to established production installations on typical modern server hardware or suitable virtual machines.  The numbers below assume that VIVO is otherwise idle; that is, not loaded with concurrent public page requests or performing multiple other background operations at the same time.

Individual page display

The time it takes to render an individual page can vary significantly depending on the types of data involved.  The page for a person with many publication citations will take longer to render than one with simple links to other individuals.  As a very general rule, your VIVO should be able to handle around 100 data items (properties) per second when displaying an individual page.  Thus, if the page for a person with 500 publication links displays in five seconds, there may be relatively little room for performance tweaking short of caching the entire page.  If the page takes 50 seconds to appear, there is very likely a serious performance bottleneck somewhere in the installation or a hardware deficiency that needs to be addressed.
