As I recall, the XT was an 8 bit bus with a 16 bit processor. It'd run 16 bit code, two samples per processor execution. Before I migrated up to a 386, I was running "Windows 286" on that lowly machine. I thought I was patient, but when I installed my first copy of Excel for Windows, I learned about 30 second refreshes. When I then output the table in graphic format, the wait turned into minutes.
