After figuring out that opcache.jit_buffer_size is specified in bytes
(not in megabytes, as RFC states) I got ~5% speedup running
vimeo/psalm (static analyzer) on its own codebase with default
JIT flags and ~7.3% with minimal JIT (1201).
PHP+optimizer (-dopcache.jit_buffer_size=0): 32.29s (100%)
PHP+optimizer+JIT (-dopcache.jit_buffer_size=50000000): 30.72s (95.1%)
