Profiling Viper

Here are some resources to profile Viper, tested on Ubuntu 22.04.

VisualVM

• VisualVM Can be used to profile Java/Scala code.
• To profile Silicon it's important to launch VisualVM with 1G of stack space. This can be done writing visualvm_default_options="$visualvm_default_options -J-Xss1G" into ~/.visualvm/<version>/etc/visualvm.conf.

JetBrains dotTrace

• DotTrace can be used to profile dotnet code (i.e. Boogie).
• Academic licenses are free.

Hotspot

• Hotspot can be used to profile applications composed of multiple processes.
• It uses perf record under the hood.
• It can show where Z3 spends its time.

Other tools

• The YourKit/JProfiler commercial profilers might be better than VisualVM, but they require a license. They provide free licenses for open-source projects, but only after adding their logo and link on the webpage of the project.
