Performance

[Thomas Baumgart]

Hi,

I noticed these differences myself in the 5.1 branch. SSD vs. HD does not make a difference, as the bulk of the processing causing the delay is happening when the data is already loaded into RAM. CPU speed makes a difference.

In master this is better (but far from ready for production use). Loading time does not differ upon the view selected to be shown after start of the application. I found another area where I can make improvements, but have not come around to actively work on it.

When I added everything else, the opening took about 8 seconds instead of 5 seconds. I am running on a fast SSD with lots of RAM so it's probably about as fast as it could be.
