You can see a discussion [on hackernews](https://news.ycombinator.com/item?id=27960865).  
There [was no dedicated discussion on discourse](https://discourse.julialang.org/t/found-this-blog-post-on-hacker-news/65386).

For me, latency is the #1 problem.  
As an example, I find the [blog post advertising Julia’s CSV.jl is 10-20x faster than alternatives in Python and R](https://juliacomputing.com/blog/2020/06/fast-csv/) to be grating, because I would prefer any of these R or Python alternatives over CSV.jl for performance reasons.  
For the sizes of CSVs I work with, the R and Python options are essentially instant, yet in Julia I need to wait 10 seconds each time to compile.

Latency is a problem we should be taking more seriously in the package ecosystem.
