I previously advised that I first noticed the performance hit in modTableField during testing for Bernd and have advised Bernd of my findings.

He has replied with this email and I also have listed my reply:

LC 6.7.3

I find:

1000 rows perfect.

2500 rows nearly perfect

5000 rows a little sluggish

LC 7.0.3

I find:

1000 rows a little sluggish.

2500 rows sluggish

5000 rows unacceptable

I have thought my self that using the Geometry Manager seems sometimes to be unreliable and occasionally seems to loose where it’s up to.

Probably your right to do the geometry in script as at least you know where your up to. The only problem is if you have a busy user interface it could involve many lines of script.

Bernd, I hope you don’t mind but I will post this subjective email onto the list.

It emphasises the disparity in visual performance between 6.7.3 and 7.0.3.

Its a shame you can’t right align numbers in 6.7.3.

All the best
