     7=== Using perf with the SDK
     8
     9The Flatpak SDK already provides perf. You don't need to install it on your host machine. To record a trace, use this command:
     10
     11{{{
     12#!sh
     13$ WEBKIT_MINI_BROWSER_PREFIX="perf record -g" Tools/Scripts/run-minibrowser --gtk ...
     14}}}
     15
     16You don't necessarily need a debug build, but it's better to have one, or a release build configured as:
     17
     18{{{
     19#!sh
     20$ Tools/Scripts/build-webkit --gtk --cmakeargs='-DCMAKE_BUILD_TYPE=RelWithDebInfo' --cmakeargs='-DCMAKE_CXX_FLAGS="-fno-omit-frame-pointer"'
     21}}}
     22
     23To display the report:
     24
     25{{{
     26#!sh
     27$ Tools/Scripts/webkit-flatpak -c perf report -g
     28}}}
