I turned off all vacuuming, rebooted and checked auto-vacuum was still off. Has something else changed in database tweak 0.6? I've rescanned since installing it, and library.db is always reported as having no waste. That wasn't the case when I first installed the previous version. The persist.db also seems to have low waste, but is ~30MB bigger than it was. Whilst custom scan scanning, the vacuum tick appeared against persist.db and then disappeared. I'm a little puzzled.
The LMS scans currently take about the same as before, ~19 minutes. The Custom Scans are back up from 1.5 to nearly 2 hours. Not the 3 hours that I recall, and I don't know why. It may be due to faulty memory (mine, not the computer!), being on the latest ubuntu 14.04 (which I only installed in mid April), or LMS 7.9, or some residual vacuuming going on. Even the first execution of my Custom Scan menus is not quite as painfully slow as it was (~ 30 seconds). I wonder whether doing repeated rescans on an unchanged library is causing less fragmentation than with a few changes or additions? I still convinced by vacuuming, but am somewhat confused! I had expected different results, and I'm trying not to let my expectations drive my interpretation of the the results. LMS 7.9 on VortexBox Midi running Xubuntu 14.04, FLACs 16->24 bit, 44.1->192kbps. Wired Touch + EDO, coax to Musical Fidelity M1 CLiC. Wireless Xubuntu 14.04 laptop controls LMS via Chromium. Meridian Explorer USB DAC to listen via Squeezelite on Vortexbox & other PCs as required. Spare Touch in loft. ------------------------------------------------------------------------ PasTim's Profile: http://forums.slimdevices.com/member.php?userid=41642 View this thread: http://forums.slimdevices.com/showthread.php?t=101469 _______________________________________________ beta mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/beta
