You may want to add this enhancement request to that list:
<http://quality.livecode.com/show_bug.cgi?id=17210>
It deals specifically with reading/parsing large files, using two
methods: the common "read until <char> form, and one using a custom
buffer similar to Mark's email earlier today. Both forms use binary
mode, so encodings don't come into play.

I discussed the performance concerns with Peter in our call last week.
As you noted, they've been working on them, and in some cases have had
significant success.
Some chunk expressions, esp. related to lineoffset, and now nearly as
fast as in v6.x, while also retaining all the features Unicode now offers.
Other forms of chunk expressions may benefit from further performance
enhancement, and similarly with arrays some performance gain have been
made in in recent versions while others are still on the to-do list.
File I/O remains an area slated for review in an upcoming version, and I
haven't yet tested socket I/O so I don't know if performance there has
changed but is obviously just as important.
Given that v8.0 is now in RC, it would seem extremely unlikely that any
enhancements not already close to completion will land in v8.0 Stable.
That said, the team seems eager to increase performance as much as
practical, and with the progress made thus far -- with v8 being much
faster in many operations than v7 -- I'm confident we'll see a version
after v8.0 that will continue this trend.
