What is the qps of a typical server?

QPS

QPS is the query rate per second, which is a measure of how much traffic a specific query server handles within a specified period of time.

Query rate per second(Recommended learning: PHP video tutorial)

Commonly used on the Internet The query rate per second measures the performance of the domain name system server machine, which is QPS.

Corresponds to fetches/sec, which is the number of response requests per second, which is the maximum throughput capacity.

Calculation relationship:

QPS = Concurrency / Average response time

Concurrency = QPS * Average response time

Principle: 80% of visits every day Concentrate on 20% of the time, this 20% of time is called peak time.

Formula: (Total PV * 80%) / (Seconds per day * 20%) = Requests per second (QPS) at peak time.

Machine: Peak time QPS per second / QPS of a single machine = required machine.

Case analysis:

If 300w PV per day is used on a single machine, how many QPS does this machine require?

(3000000 * 0.8) / (86400 * 0.2) = 139 (QPS).

Generally it needs to reach 139QPS because it is the peak value.

If the QPS of a machine is 58, how many machines are needed to support it?

139 / 58 = 3
