@amrishlal Firstly, note that preincrement is only banned in loop bodies: https://github.com/apache/pinot/commit/0069fc3545b558cf7e49bccac4bf37a614433e48 this probably alleviates your concerns. Regarding how to increment loop induction variables, the reason to look at disassembly if you are concerned is that what you see is not what you get when Java executes on modern JVMs; the choice of preincrement and postincrement usually makes no difference to JIT compiled code. That benchmark isn't very well designed and isn't measuring what it purports to be. HotSpot has tiered JIT compilation which warms up as code executes. It does lots of smart things, like vectorizing loops (so neither pre nor post increment will be used) figuring out the variable `i` isn't used, and it even can eliminate the loop entirely. Benchmarks should be run with JMH to avoid these kinds of pitfalls, and JMH includes the perfasm profiler which correlates perf output with disassembler output, which allows you to dig in to what code actually executed during the benchmark. This benchmark below demonstrates this quite well. It has three kinds of loops 1. the first one can be autovectorized 2. the second one can be unrolled but not autovectorized 3. the last one uses a `Blackhole` to prevent any unrolling There are two flavours of each loop: preincrement and postincrement. ```java import org.openjdk.jmh.annotations.*; import org.openjdk.jmh.infra.Blackhole; import java.util.concurrent.ThreadLocalRandom; @State(Scope.Benchmark) public class Increments { @Param("1024") int size; private int[] input; private int[] output; @Setup(Level.Trial) public void setup() { input = ThreadLocalRandom.current().ints(size).toArray(); output = new int[size]; } @Benchmark public void autovecPre(Blackhole bh) { for (int i = 0; i < input.length; ++i) { output[i] += input[i]; } bh.consume(output); } @Benchmark public void autovecPost(Blackhole bh) { for (int i = 0; i < input.length; i++) { output[i] += input[i]; } bh.consume(output); } @Benchmark public int reducePre(Blackhole bh) { int sum = 0; for (int i = 0; i < input.length; ++i) { sum += Integer.bitCount(input[i]); } return sum; } @Benchmark public int reducePost(Blackhole bh) { int sum = 0; for (int i = 0; i < input.length; i++) { sum += Integer.bitCount(input[i]); } return sum; } @Benchmark public void blackholedPre(Blackhole bh) { for (int i = 0; i < input.length; ++i) { bh.consume(i); } } @Benchmark public void blackholedPost(Blackhole bh) { for (int i = 0; i < input.length; i++) { bh.consume(i); } } } ``` This benchmark was run on jdk11 on ubuntu, with the command `taskset -c 0 java -jar target/benchmarks.jar -wi 5 -i 5 -w 1 -r 1 -f 1 -bm avgt -tu ns Increments` Firstly, there is no difference in performance - any difference is well within the noise: ``` Benchmark (size) Mode Cnt Score Error Units Increments.autovecPost 1024 avgt 5 156.744 ± 0.416 ns/op Increments.autovecPre 1024 avgt 5 158.390 ± 0.096 ns/op Increments.blackholedPost 1024 avgt 5 2798.470 ± 2.657 ns/op Increments.blackholedPre 1024 avgt 5 2798.259 ± 2.553 ns/op Increments.reducePost 1024 avgt 5 456.012 ± 0.267 ns/op Increments.reducePre 1024 avgt 5 455.922 ± 0.299 ns/op ``` What's interesting is that the generated code is identical in each case. Firstly, `autovec*`. In each case, the loop strides over 64 integers at a time (8 256 bit registers). The loop increment is `add $0x40,%edx` (add 64 to the induction variable) in each case. ``` ....[Hottest Region 1].............................................................................. c2, level 4, com.openkappa.runtime.inc.generated.Increments_autovecPost_jmhTest::autovecPost_avgt_jmhStub, version 472 (464 bytes) 0x00007fd6f435aff4: vzeroupper 0x00007fd6f435aff7: add $0x30,%rsp 0x00007fd6f435affb: pop %rbp 0x00007fd6f435affc: mov 0x108(%r15),%r10 0x00007fd6f435b003: test %eax,(%r10) ;
