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:
“Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.”
—G.C. (Georg Christoph)
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
“There are people who think that wrestling is an ignoble sport. Wrestling is not sport, it is a spectacle, and it is no more ignoble to attend a wrestled performance of suffering than a performance of the sorrows of Arnolphe or Andromaque.”
—Roland Barthes (1915–1980)
