[tdf-discuss] Cores and threads


Hi all

Why doesn't Calc (at least under Windows...) use all available cores and
threads to speed up operations?

Opening a heavy (200k lines x 26 cols) xlsx file takes 6 seconds in a Intel
Core i5 (2 cores, 4 threads) using MS Office 2010. I can see the first 3
threads briefly going up to 70% load and it's loaded.

Using Calc 4.0.2 after waiting 5 minutes watching the first thread at over
85% load (and the fan whirring like crazy), I gave up waiting.

Is this a compiler limitation? A code limitation?

Regards,
Pedro
