as the title says...

i would like to reduce the system i/o load by have it not rescan stuff it already scanned.

is that possible?

It already saves (caches) the index, but will still reindex because the files could have changed since the last run. I would be open to a PR that implements an option for this

Hey @felixfbecker,

We did a quick check and this issue looks very darn similar to

This could be a coincidence, but if any of these issues solves your problem then I did a good job :smile:

If not, the maintainers will get to this issue shortly.

thanks for redirecting my request.

i wouldnt exactly call this a bug, its more of a feature request that might help with the cpu load thing mentoined at #465

ya, i noticed the caching (thanks btw. @felixfbecker , so if its already caching, one "might" make a "directory checksum" type thingy and then just compare the dirs for changes. afaik most filesystems that i know have directory changes in the "directory entry bit" (size..., date modified...).

Where is the cache stored?

In the standard cache locations depending on OS. Check the FileSystemCache.php file for details.

What if we do not reindex if the cache has 24h or less?

Then the index would become out of date.

What if we do not reindex the full project but only the the files when open?

Then most IntelliSense features would not work.

What if we renice the reindex so it doesn't block the CPUs making the IDE useless for the first 10 minutes every time we open a project?

Then you would renice the whole language server. The indexing is not in a different process.

I'll continue the discussion in gitter.
