------------------------------------------
Summary: PureJavaCrc32 vs j.u.zip.CRC32 benchmark and probably replace.
Key: IGNITE-9272
URL:
https://issues.apache.org/jira/browse/IGNITE-9272 Project: Ignite
Issue Type: Improvement
Components: general
Affects Versions: 2.6
Reporter: Stanilovsky Evgeny
Attachments: BenchmarkCRC.java
I see that Ignite has its own crc32 realization called: PureJavaCrc32 and from desc it seems to be : _The current version is ~10x to 1.8x as fast as Sun's native java.util.zip.CRC32 in Java 1.6_ But my jmh tests show opposite results.
+ If it really so, looks like backward compatibility would be easy, all that need is just to take lower part of long form zip.crc32 realization.
