(2017) The open nature of the environment led to data loss and corruption: crashes or forced restarts corrupted the Squeak image, faulty email synchronization scripts deleted server data, ad-hoc scripts sometimes created incomplete Person instances. The authors identified the need for transactions, backups, and crash recovery features. Storing all objects in memory limited scalability. And there is no mention of "performance" in the whole paper.
