Energi consumption difference

[oftit]

Hi all

Does the computer use more energy by connecting to the internet and checking mails than doing delay()?
In code:

Code: Select all

Repeat
ConnectmailServer()
Check mails()
DisconnectMailServer()
ForEver

Vs.

Repeat
ConnectmailServer()
Check mails()
DisconnectMailServer()
Delay(10000)
ForEver

Which one consumes the most?

Thank you

The first one uses more CPU cycles and thus more energy.

Oh ok. Thank you.

Not only that but it could cause a DoS on the mail server.

I would actually recommend running the code in a separate thread with a delay of one minute. Not that 10 seconds is bad, but when dealing with servers one should try to cause as little as possible traffic. If 1000 people were using a program to check the same mail server every 10 seconds that would be a total of 100 requests per second.
