Assuming the compile was the only major load in your old machine (no video or music en/decoding running at the same time, no virus sending spam all over the place, no defrag running at compile time) perf of cpu/memory/video is nearly constant. Only with the HD you can have wildly fluctuating results, as HD perf is influenced by
the amount of free space left,
the pattern and localization (absolute and relative) of free space left,
the pattern and localization (absolute and relative) of the files needed to read,
the fragmetation of the files needed to read
(the pattern and localization (absolute and relative) of a dynamic swap disk can influence memory speed as well)
IF there are a few "brittle" sectors on the HD the OS will try to read/write again and again, and this is especially expensive, as the operation breaks the read ahead pattern of the HW cache of the disk.
There are also few special cases if the OS is installed on a small separate partition or disk, as sometimes the "personal" folders of the OS have to fight for space on an otherwise nearly empty data disk. Hint: dynamic swap disks are often on that partition.
Easy eplanations could be that you deleted a few GB of old, unneccesary data in preparation for the HW move to the new machine or cleaned ot your temp files and internet caches <g>.
If you want to reuse the old HDs and or plan to have the old pc still working, I'ld try to get to the bottom of those compiling speed differences - such fluctuations are mostly explainable or can be a symptom of bad pc health. And data resurrection can be very costly.
