Pre-patch:

Log on, open mailbox and collect all unsold items.
Open ATSW and queue items to replace those that sold. (This part took awhile, since I was manually tracking sales.)
Head to profession trainer for mats to create items.
Head to AH, craft items while running Cancel on all undercut.
Post.
Head back to mailbox and pick up cancelled auctions.
Head back to AH and post again.
Log off.

Except for step 3, this process normally took less than twenty minutes. I did this twice per day.

Here's how I currently work now:

Log on, open all mail (including cancelled and successful auctions).
Go to AH, cancel all undercut.
Go back to mailbox, open all mail.
Go back to AH, post all.
Open Glypher, scan glyphs - get profitable - add to queue.
Head to Dalaran vendor, trade inks, buy parchment.
Back to AH, craft glyphs.
Post.
Log off.

It seems like I take less time now than I did before, but I'm also only posting about 250-300 auctions at a time whereas before I was posting 600-800. I know I'm missing some sales because I don't have certain glyphs made, and so I'll sometimes spot check the AH to see what's selling and what I could maybe make in addition. This way, though, I'm not manually adding things to my queue as I check my mail, so it's take a bit less time overall.

you might think that, but you only have to set it up once. As opposed to having to drag every single glyph into the AH window and make sure its posting at a reasonable price, all I have to do is press post then hit yes like 336 times and I just posted 4 of every glyph on the AH.
