great to hear that - we welcome additional contributions. Just let us know in which area you're most interested in (e.g., algorithms, APIs, optimizer, runtime, etc) and we could identifying a couple of tasks to get you started.
Regarding the performance numbers, I am not able to see the details. Also could you share which operation was causing the large GC overhead - maybe we can improve the runtime for the specific scenario. Thanks.
