[wp-hackers] Improving WordPress' Performance WAS Changing MySQL

Besides the DB, the entire frontend is also just as inefficient. Take a look
I've launched several clients with LightPress, because I was custom-coding
their entire site anyway. But for the average user, that's just not an
LightPress is a total revamp of the theming system and the GUI. It's
installed as a plugin on top of WP, and is _NOT_ a fork of WP.
Unfortunately, development there is (understandably) slow.
My point in all this isn't that WP sucks or that you should use Lightpress
along with it, but rather that from the very bottom (the database) to the
very top (the frontend), WP is inefficient. Very inefficient.
With WP 1.5 that wasn't a problem. *THEN* it was "just a blogging platform,"
but now, WP is much, much more. The sad thing is, WP is getting too large to
rewrite. Because a rewrite is the only thing that can fix it. And a rewrite
at this point would kill compatibility.
Ideally, we'd say 'screw compatibility,' release 2.1, take a 6-8 month break
from coding new features and in this time re-create the database taking
advantage of all MySQL-specific optimizations, bump up the MySQL minimum
version and take advantage of all the new performance features offered, and
then re-implement LightPress as a part of the core. The actual WP code is
marvelously well-written, clear, and fairly concise compared to other
projects of its size - only the frontend needs to be redone per the
But that's not going to happen. I don't see why not, Firefox was rewritten
from scratch several times (not that it helped, Fx's code is absolutely
ghastly and leaks memory more than Hoover Dam has water) - and that was a
MUCH bigger project than WP.
The only thing is, Firefox was rewritten to improve the quality of the code,
and not the performance. i.e. the rewritten Firefox was kept 100% backwards
compatible during the rewrite. However, for WP, that would require the
breaking of quite a few plugins just to make it even slightly faster.
No matter how you look at it, WP is horribly inefficient and now it's
definitely big enough that this warrants a second look. We need to do
something, the only question is, what?
As far as the DB goes, I feel we can (if we wanted to) rewrite it without
breaking compatibility, since we just have to keep the functions the same.
Officially, WP doesn't support plugins or themes that grab info from the
database themselves - that's what the hooks are for, so we don't have to
worry about breaking those kind of things.
But no DB-rewrite is complete without rewritten functions (the LightPress
bit), and that's a bit of a conundrum. After all, WP's biggest advantage is
the millions of plugins and themes and the huge community that builds them -
not something to be taken lightly or trifled with in this manner.
.... I hate endings like this.. Please, someone, think of something!
