The delay is too long.

@jlelong The delay before starting builds, 2 sec, is too long. What is the purpose of this commit, aa5e6cc?

[jlelong]

The commit aa5e6cc was related to #1811 and #1919 (we watch PDF opened inside VSCode for automatic reload). The idea was to make sure the write process was indeed finished before triggering a fileChange event. I simply used the default value for awaitWriteFinish(see https://github.com/paulmillr/chokidar). It may not be needed for .tex files (except in #1811) but I think this is required for .pdf files which typically takes longer to be updated when they are generated by external tools. Maybe, we could change the default 2 seconds for awaitWriteFinish.stabilityThreshold. I did notice pay attention to the default 2 second delay, which is too long I agree.

I am not sure the delay is really necessary. How about making it configurable?

What is the status on this? Is the delay configurable?

For smaller documents, it used to be that hitting Cmd+S refreshed the PDF preview almost immediately, which was great.

Now, whenever I need to make a tikz figure for instance, where I need quick feedback to see what my changes look like, I have to wait for this huge delay, which quite literally ruins my productivity doing this sort of tasks.

It will be available in the next release. Use the previous version until it. See https://github.com/James-Yu/LaTeX-Workshop/wiki/FAQ#install-older-version.
