QPS Query Per Second 추정치

 

 

Query per Second is really important to estimating web site's scale

 

Let's assume the DAU is approximately 1,000.

 

24 hour = 1,000

 

1hour = 1000/20 = 50

 

60 minutes = 50

 

1 minutes = 1 requests.

 

it can simplify the calculation.

 

but this web sites use the AI requests.

and it takes about 10~15 seconds.

 

 

so, this sites can not process the just 1 requests.

and it is wrong to design the architecutures.

 

 

but if you use the cache, it can be processed the normaly.

because most of the parts are in the cache.

and cache hit rates are over the 95%.

 

1 minutes = 60 requests 

cache hit reate 95%

 

not cache rates is 60* 0.05 = 3

 

so, 1 minutes  = 1 requests = 10~15 seconds api limit

 

Assuming a scenario where the cache hit rate is low...

 

 

it can processed normally during 2~3 requests at the same time
