Linux perf profiles of CompileTheWorld with libgraal show that CompilerToVM.getComponentType is the most expensive JVMCI VM entry point with almost 2% of total execution time:
+ 1.87% 0.04% [.] c2v_getComponentType
+ 0.54% 0.00% [.] c2v_installCode
0.39% 0.00% [.] c2v_getResolvedJavaType0
0.04% 0.00% [.] c2v_resolvePossiblyCachedConstantInPool
0.03% 0.00% [.] c2v_interpreterFrameSize
0.03% 0.01% [.] c2v_isAssignableFrom
0.02% 0.00% [.] c2v_translate
0.01% 0.00% [.] c2v_getIdentityHashCode
It's worth caching the result of this call.
