instructions per second (Instructions per second (IPS) is a measure of a computer's processor speed. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads typically lead to significantly lower IPS values. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a numeric value such as thousand/kilo instructions per second (TIPS/KIPS), million instructions per second (MIPS), and billion instructions per second (GIPS).

In a more restricted view, the term is usually used by DBMS vendor and user community to refer to the number of database transactions performed per second. WK Alexander Demidov) |
