View Full Version : Hmmm - Maybe this scanning speed isn't normal?

Hi everyone,

After reading the "other" thread about slow scanning speeds I started thinking that my scanning times weren't normal or to be expected.

First my setup:

SS 2.3.1 (8468) running on Win2003 SBE SP1, 512MB RAM, P4 1.6Ghz.
Music is stored on a 300GB USB2 drive connected to a Linksys NSLU2. All connected to a 100mb switch.

All music is MP3 from 128kb to 192kb VBR. Currently have approx 12,500 tracks and 900 albums in the format:

\artist\album\track.

SS has the UNC folder name of \\server\music as it's location for the music files. I have nothing set for playlists as I don't use these.

A full scan takes 2-3 hrs and a rescan takes about the same.

I've just kicked off a full scan with the d_scan debug switched on and can see the log.txt updating but to be honest have no idea what to look for to see if there's a problem.

Would you expect this to be faster?

cheers

Steve

Seems decent for a NSLU2...

Yes, connected over a network via USB2 from an NSLU2, rescanning is when you'd notice the slowdown.

You don't need internal IDE/SATA speeds when you're serving music, but rescan needs as much speed as possible. Lots of I/O requests, particularly for 12.5K tracks.

You must notice your network activity light on your router/switch going nuts on a rescan.

You have 3 items slowing you down here: USB2, 100 Mbps Ethernet and the NSLU2. I find my USB2 drive directly connected to my PC gives real speeds of 125 Mbps (a far cry from the 480 Mbps USB2 spec) and 100 Mbps Ethernet gives ~85-90 Mbps real speed. The NSLU2 will slow things down further - how much I don't know.

My scan takes about 2 hours as well and I have all my music on an NSLU2 as well. That's scanning 9076 tracks. I schedule my scans to run in the wee hours so I'm not affected by it. If I really need to access new music right away, I'll just force a read by browsing the music folder.
