Altium Designer 17 DRC taking for ever
Start by selecting only the important rules that you want checked. The first step would be to ensure that you do not have an excessive number of rules set up in your Design -&gt; Rules settings. Once those are cleared out you can go to Tools -&gt; Design Rule Check and change the settings for each element under the Rules To Check heading in the left panel.

Additionally, in the Design Rule Check window change the "Stop when ___ violations found" to something manageable (for example, 100).
