One and a half minutes is not slow, and your Windows is running a tedious boot services process which continues on well after the GUI appears. Don't be fooled by that. Try logging out of Windows immediately after the GUI comes up. There are several systemd services which you can turn off to speed up Linux boot time, but then you will have to start them after boot.
I should probably add to this that you can get more information from the boot journal. To run it maximize a terminal because the journal will most likely be 800 to 2000 lines in some cases but you will be able to better isolate boot issues. Use up/down arrows on your keyboard to scroll through the messages in the terminal. As far as your question about swap shouldn't make a difference unless you made an error trying to configure swap, or left a swap partition on the drive from a previous installation, but if you did by accident a notice of a running cron job would appear and then a notice of failure to initialize/locate a partition. Also you may be right about network being the issue, but I would also make sure that your system has all the most recent kernel updates first as Ubuntu is in the process of developing some changes to that software.
