It probably depends on how much more the other job is paying.
For example, I would ignore a 10% raise; my reaction to 20% raise would depend on whether I like my current job; and a 50% would certainly be a strong temptation, unless it is a kind of job that predictably sucks.
The companies that complain that they cannot find a senior developer, they usually do not offer 50% more; or if they do, they carefully hide the fact from the unsuspecting audience. It is their choice, of course. I am just saying that it indeed is their choice.
