Top Performance Problems And How to Test For Them

Ever wondered why really had a problem or why BestBuy was down on Black Friday? Or what is the real reason behind that maintenance screen when you just tried to access your online banking system? If the system crashed under the load – why didn’t they test it properly? Or did they forget something?

We want to share the top reasons why applications that impact our lives have failed when we tried to access them. We dig into the technical details on why they failed and why testing is partially to blame for not finding these problems early on before it made the news.
