Hi All,
I have an enterprise DB application that once used DO to move some
files around (images and zip files, mostly). After some serious
testing and lots of reading, I decided to move this to a few different
BLOB fields in the database. Despite major warnings from people, I've
found that images work great (specifically, NSData/NSImage). I can
notice a very minor speed drop a few milliseconds, but being able to
drop DO and it's woes is completely worth it.
Unfortunately, I didn't quite test the zip files, figuring it would be
the same. I'm using Serge Cohen's MCPKit (aka SMySQL), which has a
nifty little function to convert NSData to a MySQL-legal NSString. On
the other end, someone on the Apple list posted a few lines of code to
bump returned data into it's original NSData object. With the zip
files (no larger then 600kb) that method takes 30 - 40 seconds to run.
On an image of a similar size, it takes 0.1 seconds on a slow day.
Does anyone know why this would be? Is there an easy way to get around
this? I suppose my understating of hex is lacking, but I always
thought a hex string was a hex string was a hex string; length was all
that mattered.
Thanks,
Ben Einstein
