FYI it's not like you have a slow download mirror, apt is doing necessary things in the background (probably database type stuff) before it starts installing the downloaded packages. It has to sort through the proper order to install things, for one.
You can monitor it with ' top ' but pretty much the only change you can make besides giving it more CPU (or putting the CTR on faster disk/SSD storage) is to renice the apt process ( -10 or -15 usually makes a noticeable difference ) or launch it with a higher nice priority.
Honestly though, you're kind of obsessing over half a minute delay while it's doing necessary processing - maybe take a coffee break while it's doing its thing and just check it when you get back
