I am not technical guy so I don't join the testing period, but hope that all things will be fine and the official version will be released to the community soon.
They released it on Friday and community is still playing with it. I think it'll last till the next public update, which actually will just continue the testing period. Hopefully, External load test will be announced soon, looking forward to it actually.
Does anyone from testing team use transaction generators for system loading? If yes, what current tps results?
No, I don't think anyone launched it yet, even if they did, I didn't caught that moment. But community is keeping quiet about it, so I assume they didn't run the generators in the end.
I also heard there are some limitations with the generators community is using, like they send txs through API and not directly to the node, which is limiting throughput very significantly.
