Postgres also had a reputation of being slow compared to MySQL.

This was due to a lot of really poor MySQL vs Postgres benchmarks
floating around in the early 2000's.  They generally tested stock
configurations (MySQL had a less restrictive out of the box
configuration) and they tended to test things like how fast can a single
client insert/update/delete data from a table.  Unsurprisingly, MySQL
won, as Postgres imposed all sorts of pesky behind the scenes protection
for your data that MySQL didn't worry about.

No one really tested it in a way that mattered, which was how the two
databases performed under concurrent load, where Postgres won hands down.
