Because of a limitation in the OS, the largest file size we can
currently read is 768M when represented as Unicode. Note the
qualification; since BBEdit represents files internally as
Unicode, a character takes up two bytes, so today's practical
limit is 384M on disk (since that'll expand to 768M when
represented as Unicode). Working around the limitation is on our
to-do list.
It's been my experience over the years that when trying to work
with files over a certain, relatively small, size, BBEdit gets a
bit too painful. The specific size has grown as hardware gets more
powerful, but on my G4/1.4 with 1.25 GB RAM, things start to get
painful at a few tens of MB;
I used to edit a ~30MB file on my G4 500Mhz machine with BBEdit
regularly and never had a problem, unless of course I was silly
enough to turn on wrap, then it all went pear shaped and dropped to
treacle-in-orbit speeds.
my similarly equipped PB is about the same. Once the file opens,
everything is usually just fine, but opening the file takes so long
that it's usually quicker just to do the job in Terminal using the
various Unix utilities. Needless to say, I often find myself
reaching for the force-quit key combo when I accidentally open on a
very large text file in the Finder that gets sent to BBEdit. Making
the situation worse is that BBEdit completely locks up during the
process, keeping me from doing anything productive in already-open
files (or saving them before doing that force-quit).
OK, well, yes, OPENING the file takes time, that's true. And yes, [n]
vi is faster. But working with a 30MB file in BBEdit is sill usually
better than working with the same file in nvi, unless it's a very
minor and quick edit/fix simply because it's overall a better tool.
As a result of this, I've never regarded BBEdit as a viable tool
for editing large files, except in a pinch. I cringe at the thought
of editing a 70 MB file,
Well, to be fair, editing a 70MB file is slow regardless of editor
choice and yes, I've even had nvi slow down and become unresponsive
with massively large files, especially if they contain any binary
characters.
