Could you, please, write more details about the type of data being rendered? As I am preparing for 0.8, I actually started streamlining some of the code and turns out that even with contracts and no futures it can perform nicely. I tried 10 columns x 23000 rows table for testing and on i7-1160G7 got:
cpu time: 15916 real time: 17002 gc time: 808
Not bad for a start.
I would appreciate to know:
- the number of columns in your test-case
- their minimum, maximum, and average widths
- whether there are multi-line cells used
I'd like to replicate that and see for myself what can be done before focusing on lazy evaluation and parallel processing (which is definitely post-0.8 feature).
Also the cell clipping/wrapping/re-flowing and the ability to specify fixed column widths is already there. That should help too.
I've just released 0.8.2 which computes certain values (like column widths) more efficiently.
@jtp - could you give it a try with that 23k rows table and share results? Also if you could provide me with more details about that test case I would really appreciate that.
You can also specify fixed column widths and wrapping/clipping/re-flowing of cell contents:
