Analyze Volume - Why such a huge time difference?

[Weasel]

I’m trying to figure out why the same process takes so much longer on one PC than the other.
Both point to the same NAS located music file Library and data base Library. Only one PC is active at a time. Can anyone offer advice? I have repeated this on different albums and had the same results.

Select all songs in the album (11 songs total).
Restore Original Volume (to give a clean starting point).
Analyze Volume, On Track Basis and On Album Basis, slider at 0 dB, clipping alert ON.

On PC 1 – completes in 8 seconds.
On PC 2 – completes in 4 minutes.

PC 1: 3.40 GHz i5 Intel CPU,10 GB RAM, Windows 8 64 bit.
PC 2: 3.33 GHz i5 Intel CPU, 4 GB RAM, Windows 7 32 bit.
Both PCs running the same AV software and no launched programs other than Musicbee.

This may sound too obvious a suggestion, but have you done the same test on local files instead of on files on your NAS?

It took awhile, but I updated my powerline hardware. Now PC 2 completes the task in under 2 minutes.
