This is a very interesting post... Since MC 11, i've always had the "feeling" that MC's network performance was slower than with previous versions. I've seen a huge speed boost with the introduction of database caching, but to me it seems, with every new build, MC got slower and slower in terms of network performance - not only when importing new files, but also while playing, tagging, searching in the database, etc. It also seems that, while MC is running (especially when playing music), network speed for all other applications is dropping dramatically. I looks like MC "sucks up" all available bandwith on my 100mbit switched network (which should be totally sufficient for playing music, by the way - who needs gigabit ehternet?
). Btw, all my media files and the library are located on a (more or less) dedicated windows server, so no "strange" NAS-like stuff is involved.
Sorry i can't be any more specific - i guess it would take alot of knowledge (and some network testing skills) to really identify a possible problem here. Just let me know if there's anything specific i could do to give you more details.
Am i the only one seeing this "speed degradation"?
