According to the "Ockham's razor" principle, "the simplest explanation 
is usually the best one."

In this case:
- The scripts are the same
- Data are essentially the same
- GAWK (3.1.6) was initially the same
- Hardware is the same (assumed)
- The OS has changed.

So the most probable cause of the loss of speed is the configuration of 
the new server. Possible issues:

- Virtual memory size (partition or fixed file).
- Network drives vs. local disk drives.
- Disk cache.
- Other processes or daemons (services) competing for memory or disk.
- etc. etc.

If the awk scripts do not use gawk extensions, then it should be 
possible to run them with other Windows awks (mawk, "the one true awk", 
...) and see if there is a difference in speed.

Just my 2c.
