FIXED: Build 2017.5040 (Win64): Folder DAT VERY slow

I’ve tested on a couple of machines and the Folder DAT seems to be WAY slower in 099 than 088. When I point it to a new folder, it hangs TouchDesigner for an unusually long time (upwards of 10 seconds depending on the folder). The same folders in 088.62560 (Win64) calculate almost instantly by comparison.

OK, I have a test file for this.

When running 088 on my laptop, the Folder DAT takes around 77 msecs to switch and search through 3 folders that each contain 100 blank .txt files .

On 099, it takes a over 16 seconds.

Woah.

Similar performance here.

Thanks for the report and the great example, we’re looking into it!

Can you report how 2017.5540 is working for you now?

Hi Ben, I am still experiencing the same behavior.
