Impact on JIRA SERVER if dashboard gadget render size increased to 100

Hi Team,

     Is there any performance issue if we change gadget render size to 100?

Thanks,

Do you mean the size of the display, or the number of gadgets?

Number of gadgets

Ok.  There's no direct impact of increasing the number alone to 100.

But if someone uses it (adds more than 25 gadgets to a dashboard), then yes, you could well see noticeable performance issues.  When a dashboard is rendered, it effectively makes a set of calls to the Jira API all the same time.  Some gadgets are very simple making only one simple call, others make several.  Some calls can be quite complex.  If your users have 100 gadgets on a dashboard, then when they view that dashboard, there are 100 potentially very intensive things being asked all at the same time, and your server could struggle to serve them all.

I would strongly recommend not increasing the number.
