@sandersn Any updates?

[sandersn]

When I updated spica to master, it compiles in 14.6 seconds on my machine. Before #17984, it compiles in 26.92 seconds. Are you still seeing oomemory crashes?

[falsandtru]

Yep, I got crashes when repeating code compiling, using gulp watch. Anyways, a compiler is still too heavy and slow (needs 2.2 min).
