TSV data affects performance in AE

Adding large TSV files with multiple columns and rows seems to bloat AE projects that link to the data.

This is especially noticeable when multiple comps and pre comps link to data via expressions. It can be improved a bit by having the data only appear in one comp and then being linked to from other comps rather than adding the data to each comp. But overall the interface still runs much slower, and exports are considerably slower when rendering comps linking to data especially when the data file contains many rows and columns. Anything that can be done to improve performance makes using data in AE much more viable

I'm experiencing the same issue. Renders slowing down significantly.
More than an update I would need a workaround or an expression to have AE look at csv as static data.

100% This. When I initially found out that I could import loads of stats/data with a CSV/TSV, I thought it was a gamechanger. I had been manually typing in 100's of data into my AE projects for years so was so excited at the possibilty of speeding up my workflow and linking everything to a CSV instead.

However, once I linked all of my text layers to the CSV, my project now runs incredibly slow. I have tried so many things to speed up the project, but the render preview is painfully slow when using a CSV to import data.

I think the issue is that AE reads it as 'dynamic data', so the slow performance is because it is constantly re-excuting the code every frame to see if the data ever changes. However my data is static and never changes, so you'd think it would be very easy for AE to run smoothly on this.

Do you have an example to reproduce ?
