[Scons-users] FW: SCons building M4 targets comparatively slowly.

Hello all.
My apologies for neglecting to respond sooner, but I was unexpectedly reassigned to another task. When I finally did return to this issue, I found that it had appeared to resolve itself after restarting my machine; the build time was now very comparable to Make (5.4s). Thinking that the issue might perhaps be related to one or more other applications I had been running in the meantime hogging resources, I decided to leave the problem and work on something else. This morning, after allowing my machine to run for several days without restart, I tried again, and lo and behold, the build now took about 29s. Feeling confident I was honing in on the issue, I quickly restarted my machine and tried another build.
It still took 24 seconds.
So now I'm right back where I began. Just to reiterate, I always check Make as well for comparison and it consistently takes about 4 or 5 seconds no matter the conditions.
As requested last time, I have created a github repo with my SCons files and source files of equivalent length: https://github.com/TonyPeterLong/scons
FYI, my OS is Windows 10 Enterprise, Version 10.0.17134 Build 17134.
Regards,
Tony.

Hi all.
I have an issue with SCons taking quite a long time for what - as far as I can tell - is a fairly trivial build. I posted a question on StackOverflow about a week ago, and although I got a couple of responses, I haven't found anything to help me get to the root of what I'm doing to make it so slow. You can find my question and my code on StackOverflow here: https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F55014873%2Fwhat-is-making-my-scons-build-take-so-long&data=02%7C01%7Ctony.peterlong%40nxp.com%7C86be5641cf6b47e8635008d6a83b06aa%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C636881368810058274&sdata=BPYiGWVo8Bf3ifOdTm86FRg5G%2FcA8lX7Z1R2W%2B5Ay48%3D&reserved=0.
Any help is appreciated.
Thanks.

Tony,
How big are the files you're running through m4?

Can you create a mock test with equivalent length files filled with "a" and create a github repo so we can try to repro?
Thanks,
