Compilation taking 30+ seconds

Hi there,

I have used Visual Studio (2015) with visual micro (1.1706.25) for two years now, and have recently purchased a new computer. After installing Visual Studio (2017) and visual micro (1.1801.27) my compilation time has increased from < 1 second, to 30+ seconds on multiple tries. Any help pointing me in the right direction to solve this?

Hi

Is this the case with a new empty project?

Which arduino ide, board and tool chain (if applicable) are you using?

Thanks

Hi,

I am using Arduino 1.8.5.0, along with a Mega 2560.

With a completely empty project (just setup() and loop()) it took 26s to compile initially, and 6s the second time.

The recent ardino tool chains are very slow. Switching on vMicro>Compiler>Parallel Builds would help but it doesn't  explain why you keep getting a full compile in the main project.

We can check you project F4 optimization settings but first let's see what you see after clicking Solution>Build on your main project. 

Switch on vmicro>compiler>verbose prior to build so we see what is happening then post as a TXT file or email to info[at]visualmicro.com

My new computer's build: (26s)

https://drive.google.com/open?id=1-gZTJT8hiPSkJQ4RHB2Z80Wl5_M_S7HF

My old computers build (two in a row): (7s, and 1s)

https://drive.google.com/open?id=1yFiZBi0YkGVNJPIbvIvt7PpDGOfHblul

It seems to spend a lot of time linking as well. Also, my new computer is way more powerful than my old one.

thanks.

1)
please switch the tool bar on the new machine from Debug to Release and then build twice and post the output

2)
on the old machine please click build>rebuild solution


then post both outputs.

Oh, totally forgot I had Debug on, here are both builds:

I believe the difference is two things:-

1) That you have arduino 1.6.9 installed on old and 1.8.5 on new. They (arduino) have been messing with tool chains for some time and older arduino tool chains are significantly faster on windows

2) Because your cached compile is so slow I would also look at your virus checker.

Can you conform 1st and 2nd build speed in arduino ide?

So Arduino 1.8.5 took about twice as long to rebuild compared to 1.6.9. So I Uninstalled 1.8.5 on my new computer, and reverted back to 1.6.9.

My rebuild times are now ~28s on my new computer, and ~16s on my old computer. However a second build has them both at ~1s which is awesome.

Here is the rebuild output:

New: (26s) https://drive.google.com/open?id=1Z064ALDzGNBo2Fl5LVJCpl_Mm9hxWO4K

Old: (14s) https://drive.google.com/open?id=16aF4E6vhTtBDKA27WArFQsVTTkLTQhli

Great I suspect that difference is either virus checker or disk speed.

If you switch on vMicro>Compiler>Parallel Build the build should be 50% quicker when libs and core do need recompiling.

Aside from virus checker causing slowness their is an update which also helps

Update: The work in progress notifications area has a download that uses a new cache system for cores. 

This should mean that you only see a few core builds (per board/properties) within all existing and new projects. Generally should be much faster unless you only ever work on one project. The option is optional and can be disabled.

After building once for a board, the 1st build of new projects with no libs in Release mode should be  < 3 secs
