Performance
Java code compiled into machine code by GCJ should have faster start-up time than the equivalent bytecode launched in a JVM.
However, after start-up, Java code compiled by GCJ does not necessarily execute any faster than bytecode executed by a modern JIT-enabled JVM. This is true even when GCJ is invoked with advanced optimization options such as -fno-bounds-check -O3 -mfpmath=sse -msse2 -ffast-math -march=native; in this case, the compiled program may or may not surpass JVM performance, depending on the operations performed by the code in question.

Famous quotes containing the word performance:
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
“No performance is worth loss of geniality. ‘Tis a cruel price we pay for certain fancy goods called fine arts and philosophy.”
—Ralph Waldo Emerson (1803–1882)
“Still be kind,
And eke out our performance with your mind.”
—William Shakespeare (1564–1616)
