[tex-live] Identifying the cause of slow compilation

it seems to me that your TEXINPUT is not optimized,, it searches file by
disk lookup instead of default database lookup (if the components contain
!! as Markus wrote). The difference is thus the performance of the file
system. It is difficult to say why VM is faster, it would be important to
know whether it locates the files on its virtual disk or on the host disk.
Anyway, in plain TeX the difference should not be as pronounced as in LaTeX
where typically a lot of packages and other support files have to be
loaded. In plain TeX you read usually just the format, tfm files and your
document. You can try to use kpsewhich to locate a file and measure
