How many requests can a Web server handle?

Formula for calculating the max capacity of your web server The servers capacity is 32 CPU cores, so when every request to the website on average uses 0.323 seconds of CPU time – we might expect it to be able to deal with approximately 32 cores / 0.323 seconds CPU time = 99 requests per second.
