| [[dido:public:ra:xapend:xapend.a_glossary:p:performance]] is the ability of a system to accomplish the required functionality at or under the required specification limits. The limits are generally provided relative to time (i.e., so-many transactions per second, so-many updates per millisecond, so-many recorded entries per second, etc.) The specifications can also include accuracy, precision, precision or even efficiency of other dependent systems as requirements. The following are some examples of [[dido:public:ra:xapend:xapend.a_glossary:p:performancespec|performance specifications]]: | [[dido:public:ra:xapend:xapend.a_glossary:p:performance]] is the ability of a system to accomplish the required functionality at or under the required specification limits.
