Not sure what you mean.

There are lots of performance disasters.

But typical it is the high level design that is wrong not
the low level code.

Example 1: a system where reports was painful slow - turned out that the
report made 6000 database queries to get the data for the report.

Example 2: a web page was painful slow - turned out that the
client side JavaScript fetched data using 2000 AJAX requests.
