   Hi,

   I guess you found the java vm settings in the Info.plist?

   beaTunes' memory consumption depends on the number of songs in your library and the number of parallel analysis tasks (editable in Preferences -> Analysis).

   The way beaTunes is currently coded (I hope I get to change this sooner rather than later), I would add roughly 100MB/parallel analysis task (that allows beaTunes to decode a song and keep the raw audio in memory). Because of garbage collection implications, It may be smart to first increase the MaxDirectMemorySize, not the general heap.

   Note, that too much memory will only slow down your system, but not speed up beaTunes. That said, there is hardly a real upper limit to memory, as beaTunes on OS X is a 64 bit process.

   Hope this helps,

   Can you give an advise based in my system ?, I want to give beaTunes with the maximum memory it can takes, but not to a point that harms the process, How much memory do you think is best.
   And how do i increase the MaxDirectMemorySize, and how much do you recommend?

   And when i increased the value, after i stopped the program, i couldn't restart beaTunes, i had to reinstall beaTunes in order to launch. reinstalling beaTunes leaved the original memory settings and i didn't have any trouble launching again

   What do you currently have parallel tasks set to (in Preferences -> Analysis)?
   (this is important for the MaxDirectMemorySize setting)

   And how many songs are in your database?
   (this is important for the -Xmx setting)

   Thanks,

   Now i have 12 parallel task, I could not work with 24 parallel task, my library is 169000 songs.

   OK. So you have a huge collection and a really fast machine. :-)

   • Install the latest version (3.0.4)
   • Make sure, beaTunes is not running
   • CTRL-Click on beaTunes3 in Finder
   • Choose "Show Package Contents"
   • in the new Finder window, go to Contents
   • Open Info.plist in TextEdit
   • Find the line <key>VMOptions</key>
   • Edit the string underneath so that it says -Xms512m -Xmx1g -ea -Xloggc:gc.log -XX:+PrintGCDetails -XX:MaxPermSize=256m -XX:MaxDirectMemorySize=3g
   • Save the file
   • Open Info.plist.template in TextEdit
   • Find the line <key>VMOptions</key>
   • Also edit the string underneath so that it says -Xms512m -Xmx1g -ea -Xloggc:gc.log -XX:+PrintGCDetails -XX:MaxPermSize=256m -XX:MaxDirectMemorySize=3g
   • Save the file
   • Now start beaTunes3
   • You should be able to further increase the number of parallel tasks - however, since you have 12 cores, it probably does not make sense to have more than 12 tasks in parallel (unless your cores support hyperthreading and can pretend to be more cores)

   Keep in mind that the settings will be lost which each beaTunes update.

   I'm curious to know how well this went.. Please keep me posted.

   Thanks,

   -hendrik

   Hendrik,

   Still have problems with VM, and the process crashes, I think, I can assign more memory, the program uses only 5GB, there still plenty more memory that can be used, the cpu activity gets an average from 700% 12 parallel task to 1400% 24 parallel task

   Hi,

   please increase the heap size to 2GB by editing that file again.

   replace -Xmx1g with -Xmx2g

   You may increase it more, if you see more OutOfMemoryErrors.

   Thanks,
