How is PV, TPS, and QPS calculated?

Term Description:
QPS = REQ/SEC = Number of Requests/sec

"The way the QPS calculates PV and machines"

QPS statistics [general use of http_load statistics]
QPS = Total Requests/(total number of processes * Request time)
QPS: Number of successful requests per second of a single process server

Single server PV calculation per day
Equation 1: Total PV per day = QPS * 3600 * 6
Equation 2: Total PV per day = QPS * 3600 * 8

Server computing
Number of servers = Ceil (total PV per day/single server total PV per day)

"Peak QPS and machine calculation formula"

Principle: 80% of visits per day are concentrated in 20% of the time, 20% times called peak time
Formula: (Total PV number * 80%)/(number of seconds per day * 20%) = Peak Time requests per second (QPS)
Machine: Peak time per second QPS/single machine for QPS = Required machine

Q: Every day 300w PV on a single machine, this machine requires how much QPS.
Answer: (3000000 * 0.8)/(86400 * 0.2) = 139 (QPS)

Q: If the QPS of a machine is 58, several machines are required to support it.
Answer: 139/58 = 3
