Adjust the heap size of Burp

Pre

For Burp better using, I change its JVM heap size.

How

Edit the binary file of Burp suite pro:

# vim /bin/burpsuitepro
​

Add a paramater after the -jar​:

java --XXXXXX --XXXXXX -jar -Xmx16G burpsuiteXXXX.jar
​

Then restart burpsuitepro, follow Help > Diagnostics​, and under SYSTEM RESOURCES, you could check that:

---------------------------------------------------------------------------------------------------------
SYSTEM RESOURCES
---------------------------------------------------------------------------------------------------------
Number of processors             16
Total JVM memory                 1.09 GiB
Max JVM memory                   16 GiB
Free JVM memory                  616.76 MiB

Total physical memory            62.69 GiB
Free physical memory             30.43 GiB
Total swap                       4 GiB
Free swap                        4 GiB
​

Finish adjustion.

By the way, the burp edition I use is from here, just clone it if you need it.
