    Scanning speed

    When I re-scan my entire collection, the speed is about 100-150 GB/hour. Is that what I can espect or is it too slow?

    I have a quite normal computer, Win7/8GB RAM/3GHz processor/2TB-disks etc.

    that seems a bit slow. I can scan 70,000 files in an hour or less on my win7 setup. Which version of LMS are you using, as the scanning got much faster starting (I think) with 7.6.x and later versions. How is the 2TB disk connected. USB direct to the computer running LMS?

    edit: one win7 laptop I use is intel i7 CPU (2.67GHz, 4GB ram, 64 bit OS). I think my desktop is also i7, but may have more ram..... about the same scanning speed on both (or on my vortexbox units).

    When I saw "100-150 GB/hour" I also thought that you music is stored upon USB drive or a slow NAS access over WIFI.

    Anyway I think that we are used to focus on number tracks here when comparing performance.

    You can see the LMS scan data for the last scan of my music collection.
    99% of my tracks are FLAC and artwork is stored pr directory. No cue files or playlist.

    Better point out that the scan below is from my work laptop (DELL M6600) which is much faster than my music server at home; the hardware listed in my signature takes about 6+ minutes.

    Note I have seen that defragmenting the harddrive can have positive effect. FYI I used my 6 core stationary at home to calculate gain values for all my library. So it was working on 6 tracks in parallel. Afterwards the rescan times was horrible.

    And yes the server version does also have and effect. I did some testing at some point.

    another example, from my work desktop (win7, 64bit, intel i7 CPU, 2.8 GHz, 8GB RAM). About 30 minutes for 68,564 files for a complete clear and rescan. Files are on a 2TB eSATA disk attached to computer.

    That's extremely slow. My system scans 34,605 FLAC files, 903 GB, in less than 12 minutes. Win2k3 SP2 32-bit, 3.16 GHz Xeon E3120, 4 GB RAM, with files on an internal 7200 RPM drive.
