for example ：TPS(Transaction per Second)： The number of transactions processed by the system per second , The derivation process is as follows ,
Current online APP1.0 try ⽤ The system is mainly for Inquiry Transactions , Transaction share ⽐40%, System ⽣ The statistics of production transaction volume is 1 individual ⽉ about 20W pen , hypothesis APP2.0 After the system goes online, the business volume will increase
Increase to every ⽇ Query class 20W, Then every ⽇ Total trading volume T achieve :
T = 20W/40%=500000 pen /⽇
The system can handle ⼒TPS deduction :APP2.0 After the launch, the trading volume is the most ⼤500000 pen /⽇, System night ⼏ Almost ⽆ Trading volume , Press 2:8 Principle extrapolation , be
(500000*80%)/(8*20%*3600)=69.4 pen / second , Rounding off 70 pen / second , Grow by business volume every year 50% Calculation , be ⼀ The system can handle ⼒ The index is approximately equal to
70+70*50%=105 pen / second .
Stable trading volume derivation : Take the system processing energy ⼒ Of 60%* Duration =105 pen / second *60%*8*3600=1814400 pen .
