Reducing memory usage
Bisq is known to be a resource-hungry application, so some users may want to reduce memory usage.
Reduce Bisq's memory usage by setting a ceiling of 4GB:
/opt/bisq/bin/Bisq is the default application directory on Linux. If you run another operating system, you'll need to replace that path with the one for your OS.
You can adjust the scaling factor as you wish, of course, and add any runtime options for Bisq as well.
To have this setting apply automatically when running Bisq from a menu icon, you'll need to adjust the launcher files to run a script with the fix in it.
1. Create the script, say
#!/bin/bash JAVA_TOOL_OPTIONS="-XX:MaxRAM=4g" /opt/bisq/bin/Bisq
2. Make it executable.
chmod +x /opt/bisq/Bisq-runner.sh
3. Update the launcher (
... Exec=/opt/bisq/Bisq-runner.sh ...
Persistent setting and Windows work-around
If you'd rather not specify the RAM parameter every time you start Bisq, you can specify it in
Bisq.cfg so it automatically takes effect every time.
First, make sure Bisq is closed.
Navigate to the directory with your Bisq binary. Using Windows as an example, this would be
Bisq.cfg should be in the
Open that file in a text editor. Look for the
[JavaOptions] section, and a line in that section that look something like
java-options=-XX:MaxRAM=8g. Change it to
java-options=-XX:MaxRAM=4g, or add it if it's not already there.
You can also try disabling the hardware graphics acceleration by adding the following line at the end of the
Save the file, close it, and then open Bisq.
