> What would be required to scale this application to handle 1000 requests per second? |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This application already handles over 3000 requests per second with ease, even with an artificial 20ms cache access latency. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Granted this is all for the same URL, and it can be slower if we will be requesting different URLs. |
