Many friends have this question: Why is the application pool recycle setting for IIS default to 1740 minutes?
Have you ever noticed the default value of the application pool recycle settings for IIS? 1740 minutes, right, so why is this number?
The question was mentioned in a blog post in asp.net.
Many of the decisions about Microsoft's products have been made after numerous considerations and surveys. But others derive from an interesting trade-off, which is 1740 minutes.
When IIS 6 is developing--this version introduces the application pool--A default value needs to be set at fixed intervals when the application pool is automatically reclaimed.
Developer Wade Hilmo recommends using 1740 minutes, or 29 hours. This is because this number is the smallest of the prime numbers greater than 24. He wants a staggered and repeatable pattern, that is, not more than once a day. In Wade's words, "you're not going to get a resonance mode (you don t got a resonate pattern)". From that time onwards, the default value became 1740 minutes.
