replace every call to toupper with one to our own tolower_ascii
This sounds like a premature optimization and since Mr. Knuth we all know that they are the root of all evil - but, and here it starts to be interesting: As the tolower_ascii method is by far the most called method we have (~60 Mio. times) and as we compare only strings containing ascii characters (package names, configuration options) using our own method reduces execution time of APT by 4% plus it avoids that the locale settings can influence us.
