How many people are dead due to elephant attacks? How many people are dead due to snake bites? How many died due to mosquitoes?!!! Obviously the mosquito is the bigger enemy. They claim millions of lives every year, world wide. Reason is, that the humans underestimate mosquito and humans are not prepared against mosquitoes.
Smaller in size, larger in number, ability to penetrate a variety of areas - these are the strengths of mosquitoes. I see very similar things happening in performance issues of apps. Developers often ignore things, thinking that those are small methods or queries or js files. When those small items are accessed by 1000s of people at the same time, small item manifests as the biggest threat to performance.
Never ignore a small patch.Never ignore a method, just because it has only 10 lines of code.
Never ignore SQL query by seeing its shorter length.
Never ignore a js file, by seeing its smaller file size.
Next time, when you do a production upgrade, if you think it is a smaller item, remember
mosquitoes.
Better ensure the speed of your app, irrespective of any small/large upgrades. One small
duck can choke the entire free way traffic.
The same thing holds good for security aspect as well. Smaller enemies are rarely seen, but
they silently do the damage.
