:: How to increase Phelix memory heap size? (Windows) (Default value is 512MB)

To allow Phelix to use more memory of your system, you have to write a line of text in file
Phelix.vmoptions
that is inside the directory
C:\Program Files\Phonome Labs\Phelix

Without this step, Phelix receives the “Out of memory” error after scan of near 7000 - 9,000 songs.

Here are 3 cases:

————————————————–
————————————————–
Case I: having 1GB of memory and near 12,000 songs to analyze.

Step 1: Open Phelix.vmoptions file with Notepad.exe.
Step 2: Clear all lines of text.
Step 3: Write in the following line (or copy & paste it from here).

-Xmx700m

Step 4: Save changes.

————————————————–
————————————————–
Case II: having 512MB of memory and near 5,000 songs to analyze.

Step 1: Open Phelix.vmoptions file with Notepad.exe.
Step 2: Clear all lines of text.
Step 3: Write in the following line (or copy & paste it from here).

-Xmx300m

Step 4: Save changes.

————————————————–
————————————————–
Case III: having 2GB of memory and near 25,000 songs to analyze.

Step 1: Open Phelix.vmoptions file with Notepad.exe.
Step 2: Clear all lines of text.
Step 3: Write in the following line (or copy & paste it from here).

-Xmx1300m

Step 4: Save changes.

• Information about Java options: link

To allow Phelix to use more memory of your system, you have to alter the max heap size setting of Java Virtual Machine (JVM). The Java options are stored in a file called Info.plist inside the Phelix application bundle.

Example: set max heap size to 700MB for Mac with 1GB of memory (this will be enough for near 12,000 songs to analyze).

1. open application folder in mymac:/Applications/Phelix.app/Contents
2. open file Info.plist with Property List Editor (double click on it)
3. find entry Root->Java->VM Options
4. set value of this entry to: <string>-Xmx700m</string>
5. Save changes.

To dramatically increase a speed of file matching process, you have to disable the audio-matcher. This can be done in Matcher strategy inspector  by deselecting the check-box Match audio data and pressing  to execute. Be sure that number of Extractor threads is set to 1. More about multithreading: .

If you want to increase a speed of audio matcher and your computer has more than one CPU units, then you might increase the number of threads.

Actions:

1. Use menu View and disable Tool Bar and Navigation Pane.
2. Use Column Controller button at the top-right corner of the results table and
   • remove the columns you don't want to see (our suggestion: Bytes, Checksum...)
   • optionally use actions: Horizontal Scroll or Pack All Columns
3. Reorder and resize the columns (click & drag the column headers).
4. Adjust size and position of the inspector frames you open.

All the settings will be preserved at the next time you start the application!
