2.6.0 is significantly faster than 2.5.0

I don't have an issue, I just wanted to say Good Job (TM) to the team working on this firmware!

I'm using this SHA256 script to benchmark my ESP8226. Comparing the results between 2.5.0 and 2.6.0-dev I'm seeing significant speed improvements:

x	2.50	2.6.0-dev	Percent Improvement
CPU @ 80Mh	~9520 iterations	~11010 iterations	15.6%
CPU @ 160Mh	~17270 iterations	~22110 iterations	28.0%

The exact same code, running on the exact same hardware is showing a 15% improvement. When you bump the CPU up to 160Mhz the improvements are even more impressive! Excellent job.

Since this really isn't an issue I'll leave it open for a couple of days so people can see it and then I'll close it.

Yes, that is caused by ESP SDK revert from 3.0.0-dev to 2.2.1 as I remember.

Prerelease version of 3.0.0 was buggy, but the devs are unable to upgrade to stable 3.0.0 quickly, because there are some hacks in Arduino, that are not working on latest NONOS sdk.

Indeed, the default is now SDK2.2.1 again.
Core 2.5.0 is using SDK 3.0.0-dev

Having our effort appreciated is rare and always encouraging, but previous comments are correct: it's the SDK that was reverted, and not really our efforts. Please see pinned issue #5784.
Closing.
