How does this perform with super large spreadsheets?

[SteGreig]

Hi, big fan of this plugin and have been using it on my site for several months now.

I was wondering - I'm looking to add a new sheet which could contain over 1000 rows and 30-40 columns - would this plugin be able to cope with that? Would it have a huge affect on build times etc.?

I need to deploy this site quite regularly and I need build times to be no more than a few minutes.

Any help or info would be much appreciated. Thanks!
