Just a thing to take into account. You are comparing OS3.9 or CWB39 that run Workbench. AKReal as default uses DOpus5, Maguellan.
Maguellan will always boot later because of all of the options it adds. For example in WB you don't see all of the files as default in a drawer, so you have to click, select that, then you open the drawer you are searching, open it and you again have to select to view all, etc, etc. If you want to see the info file you've got to use DOpus instead, the same if you want to extract a compressed file. With DOpus5 you just move it from a drawer to another viewing as files and it's uncompressed, or if you want to see the files inside a compressed file, you can click on it and they will be shown too.
In fact all of the options DOpus has, and that's why it's a so popular program were added for Workbench so you could make things easily (or just make them). The authors later had some problems with his company and then they rewrote the program creating a new full Workbench replacement, DOpus5.

And many more things. So if you want to compare them, or if you want a faster booting use Workbench in AKReal.
