An observation on performance with large files.

I have noticed that trace files with a large number of sessions or flows take longer to load than a similar trace with just a few connections. This makes sense because of the work needed for each flow. As part of this testing, should we add the number of connections as well as number of frames to the mix?

As part of this testing, we should use a series of standard traces that let us test and compare various configurations. I would be happy to contribute some traces.

Hi Ronnie,

This is great, sounds like very important work towards the usability of Ethereal. The captures I work with on a daily basis tend to be fairly large (200,000+ frames, 800,000 or more per capture isn't unheard of), and speed is by far my #1 concern at the moment.

I'm not sure what I can do, but I'd love to help however I can - perhaps with the gprof stuff?
