Consider code like:
```
void test(Object o) {
    switch (o) {
        case X1 -> {}
        case X2 -> {}
...(about 100 cases)
```

this is much slower that writing this as:
``
void test(Object o) {
    if (o instanceof X1) {}
    else if (o instanceof X2) {}
...(about 100 cases)
```

Attached is a JMH test, which gives these results:
MyBenchmark.testIfElse100 thrpt 5 512697.015 ± 19581.020 ops/s
MyBenchmark.testSwitch100 thrpt 5 31815.371 ± 261.291 ops/s

I.e. the switch is 15+ times slower than the if-else cascade.
