VS2017 CE long compile times with new installation (Read 3089 times)

	I have a brand-new XPS-15 with new, default installations of VS2017 CE and Visual Micro. The only VM setting I have changed is to set the 'Auto Open Serial' flag to TRUE. I'm using the 'Visual Micro (no IDE)' selection in the 'configure IDE locations' field rather than installing a version of the Arduino IDE. This new laptop is at least twice as fast as the Precision M6700 it replaces, but the compile times are at least twice as long. BlinkTest takes well over 8 sec to compile, even with no changes (just pressing F7). I have uploaded a ZIP file containing verbose outputs from two consecutive compiles with no code changes between compiles. What am I doing wrong here? TIA, Frank

	This is normally caused by virus checkers or anti-malware software. Try switching off "vMicro>Compiler>Shared Cache For Cores" Otherwise you just need to exclude the temp build folders from your virus checker.

	Tim, Yep - you were right; my AV was also brand-new and not excluding anything by default. When temporarily switched OFF, BlinkTest compile time was reduced to about 2 sec. I think that disabling 'Shared Cores Cache' further reduced it to less than 1 sec - hooray! Thanks again Frank

	Great. yes the shared cache has to copy the core.a to the build folder each time which might take a second. However new projects and examples will compile in a couple of seconds as opposed to 20+. The shared cache also dramatically reduces disk usage because not shared has a copy of the compiled core for every project+board+configuration.

Tim, At present, I am temporarily disabling run-time scans entirely, as I'm not sure where the temp build folders are - can you tell me that? TIA, Frank

	If revie the vMicro menu it will help you. Switch on verbose then you get to see all paths in the build output. There is also an option to always show the build folder in the the compiler output In the build output look for a "Coping cached core" message when Cached Cores is enabled.
