However, the io processing has been noticed by my ISP hence my attempts to reduce it.
If your ISP is poking into it that much, it's either time to renegotiate with your ISP to make that a permitted activity, or get any one of the four million ISPs that won't care.

Most ISPs charge for network bandwidth and disk storage, and would never care how many times you call read() or write().
