+#### <a name="recommendation-qbm"></a>`QBM`: Use Quick Build Mode for Faster Builds
+
+Consider using the quick build mode (`-Ob`) to speed up your builds during development.
+More precisely, this mode reduces the number of optimizations performed by the Graal compiler and thus reduces the overall time of the [compilation stage](#stage-compiling).
+The quick build mode is not only useful for development, it can also cause the generated executable file to be smaller in size.
+Note, however, that the overall peak throughput of the executable may be lower due to the reduced number of optimizations.
