I was able to build the arm64 version of latest preview on my macbook. The startup was phenomenally fast compared intel builds. Is this coincidence (perhaps libraries were cached from the build process), or can we expect an increase in startup speed (which has been very slow on intel builds).
It’s not a coincidence - the x86 builds need to go through Rosetta and it’s very slow (happens serially as they are loaded). I looked to see if we could do some kind of preprocess to do the do it in parallel but really just putting our effort into distributing the arm64 builds is a better use of time. It’s a matter of updating the download servers and getting the extension builds in place. Stay tuned.
Nice. That speedup itself is a significant gain. Looking forward to the official binaries.
