The micro-optimization fallacy.

Before you dive in to this too far, spend a bit of time reading the papers Rob Pike and Brian Kernighan have published over the years.

Also, consider the latency of a network connection vs. the speed of the CPUs processing the data travelling to/from them.  Is the CPU you are using to parse your IMAP/SMTP stream so slow that it cannot do a 'c = tolower(getchar())' in real time?  Is it slower than your network link?  Even my ancient pre-Android phone can keep up with that.  Let alone the group of mail servers I run that manage to push through several hundred messages a second.
