I have searched the forum a little and I could not find any definitive information about how phplist performs and if it can scale up. Has anyone ever produced a benchmark for this? If i was involved in the development i would definitely like to see how each release performs compared to the previous one in a professional CI approach.
What I would be interested in is running a set of big mock list campaigns for small, medium and big mailout content and see in lets say in 1 hour how many emails php list can send to an SMTP server (a dummy one to avoid generating actual email traffic) and also how it performs in terms of memory, CPU, file, db access bottlenecks.
If anything as such exists please let me know.
p.s. I know that the ultimate speed also depends on maybe other factors but as phplist is its own monolith I am really curious to see how it performs.
