Try to overclock a test microSD (please, don't use your main one) to check if it get any faster:

Can you have 2 simultaneous microSD cards on your Raspberry Pi 3B?
One microSD card for OS, Lazarus and RDBMS and other [microSD card] for your project to be compiled and database files?
Maybe sharing IO process might speed up your project compiling.
I have single RPi 3. When I have time, I will see how much overclock helps for SD card.
I do not think I can use more than one SD card on RPi3 and I also believe, bandwidth is shared between sdcard, usb ports and wired ethernet port. So, even it was possible to have two sdcards on a single board, bandwidth will be still same for both together.
Though, USB speeds now I am observing is way above sdcard speeds. Considering USB being faster about 5 times, I am happy for now.
Thank you for the help.

I use a ssd over usb and it is 10 times faster as a class 10 sd card. One one of my pi's I only boot from SD and run raspbian jessie from ssd. Another one similar runs from a 5400 usb normal disk, also fast,
but yet two other ones run from sandisk class 10 micro sd. The speeds I mentioned are from the sd cards.
