Slow processing of compilation/linking messages [message #45808]

I spotted a performance problem with processing of large amount of compilation/linking messages.
Attached archive contains profiling information which I collected using Intel VTune.
I ran Win64 version of TheIDE built from a couple days old source code.

TheIDE.csv - data in csv format.
TheIDE.xlsx - data pasted into Excel.

Please take a look at a line below. It takes 114 second to build a package.

MakeBuild::BuildPackage	114.355s

Attachment: theide.zip

Just to be sure I am reading it right:

I see that our problem is that it spends 30 seconds in ConsoleLine and 20 seconds in ProcessEvents. Is this correct?

BTW, any hint for testcase? Smile

It is all about Ide::FindLineError.
Data is taken from the csv file.

A test case is simple. You need to compile something that has a lot of error messages.
In my case I tried to compile 32-bit code using 64-bit version of TDM-GCC (by passing -m32) and linking against 64-bit libraries. Smile

This is an artificial test case but it highlights the problem.

Thanks.
