Really? Isn't there an upper limit in terms of transactions per time period?

The scalabity problem was partly solved by the introduction of the Lightning Network in the ecosystem https://lightning.network/

As Lightning Network ramps up, and if it is able to get a significant amount of usage, the upper limit in terms of transactions per time period is basically infinite.

Without Lightning then yes the amount of transactions-per-time-period is very limited.
