Hi Brett,
I ran your benchmark on a Windows11 Pro 24H2 / ARM64 / JDK 21 system
and can reproduce your findings that
CharSequenceCharAtBenchmark.testString has weaker performance.
I also added these benchmarks:

public int testStringBuilderAsCS() {

Thanks for the reviews!

Ensure an initial overestimate of the root
Ensure an initial overestimate of the root by doing 1st ite
I've added support to vectorize `MoveD2L`, `MoveL2D`, `MoveF2I` and `MoveI2F`
nodes. The implementation follows a similar pattern to what is done with
conversion (`Conv*`) nodes. The tests in `TestCompatibleUseDefTypeSize` have
been updated with the new expectations.
Also added a JMH benchmark
Thanks Johannes for another test case!
Hotspot compiler investigation concludes this is due to inlining limits; an
issue https://bugs.openjdk.org/browse/JDK-8364043 has been created. The guess
for now is that limits are reached on different platforms inconsistently.
