I know the improvements like this one, but Labels need more love.

The recent test reveals that the "slowdowns at the very start of running the mod, and subsequent slowdowns at the start of every component" still prevent modders from adding labels: post

I've done an additional test, it seems that adding labels to the components with LAF doesn't increase the install time much. Maybe the problem is not entirely labels but also LAF? Or some other thing?

In case you would like to try various weidu code changes, you could just put them in a new branch, I can compile weidu, run tests and report back.

Testing Suite, you can point to the different weidu.exe: https://github.com/ALIENQuake/LabelsTest

Hopefully this is a link to the relevant version of the tp2:

No, I’ve just been away. I’ll dig out a copy when I get home.

@wisp I think that you need to provide new weidu (BETA?) if you wana get DavidW to try it again.

Having WeiDU cache the parsed TP2 for ID_OF_LABEL reduces the time to marginally slower than using the plain component number (which can't really be helped since resolving something into a number is always going to be slower than starting with already having the number), but solves the troublesome parsing times. If further optimisations are necessary, I'm going to need a problematic case to profile.

I don't suppose you still retain your LABEL implementation? If so, could I have a copy of it? Or a debug file from one of these slow installs?

An unsophisticated test with 150 LABELled components and 149 REQUIRE_PREDICATE MOD_IS_INSTALLED ... ID_OF_LABEL takes about 1.5 seconds to install for me, with about half that time being spent on processing ID_OF_LABEL (mostly in parsing). The implementation of LABEL is a little work, since every time a LABEL is processed, it's resolved in order to check for duplicates and such. ID_OF_LABEL is a bit worse, since it loads and parses the target TP2 file every time it resolves a label. That's perhaps something that could be optimised, but I'd have to look into it in greater detail.

A note about LABEL: in some circumstances it significantly slows down WEIDU.

I just rewrote SCS's tp2 file (which is structurally very minimal: no content in any component except REQUIREs, FORBIDs, DESIGNATED, a marker file, and a function call) to use LABEL. So every component got a label, and I did internal checks via REQUIRE_PREDICATE MOD_IS_INSTALLED blah ID_OF_LABEL blahblah. Weidu hung for about 10 seconds whenever I ran it. After a couple days I found that so annoying that I went back to using DESIGNATED or marker files.


Now: SCS has 120-odd components and 150-odd checks for components, so I appreciate it's an extreme case. But I thought it was worth flagging, since I think LABEL has hardly ever been used in the wild and the code / method of implementation might not be optimized. That's especially relevant if Alien's GUID gets installed and it uses the LABEL method as a code base. (Don't bother speeding up LABEL just for my sake, though - I'm actually perfectly content with my current implementation.)
