Qt Creator slow to open large files

Harjit

Qt Creator 4.10.1 on Windows on an i5-8400

I compiled a code base of approximately 100 files and it had a lot of issues. So, I went to Compile Output and copied it to the clipboard, created a scratch buffer and pasted the output in.

The buffer was around 50,000 lines.

Searching it was incredibly slow - it took seconds to enter the search text and for Qt Creator to find it.

I'm guessing Qt Creator was building up an internal representation but it shouldn't be this slow. Is there a way to tell it to not parse the text and treat it as text?

I took the output and disassembled it and it gave me a 130k lines and loading that and searching it was very, very slow - many seconds.

To make sure I wasn't crazy, I repeated this in Visual Studio 2019, Community Edition and it these tasks were instantaneous.

Hi @Harjit,

no direct solution to your problem, but you can search, filter and even edit! the Compile Output, so no need to copy&paste the contents.

@aha_1980 The challenge I have with doing things in the Compile Output pane is that if I click in the pane, it takes me to the offending line. So, searching isn't feasible.
