October 13, 2022 Automatically-created threads (just want to understand) | ||||
|---|---|---|---|---|
| ||||
 | Hello, after migrating a project from LDC 1.10.0 to 1.30.0, I now see (1) a significant speedup & less memory usage - many thanks for that - and (2) for each process (originally single-thread), up to 1+N_CPU threads, which are active once in a while. These threads are automatically created, unless I am mistaken. Just to understand: what are these threads for? Do they have anything to do with disk I/O? Something else? Best regards, | |||

Something else? Hi; these are created and used by the GC (by default), see https://dlang.org/changelog/2.087.0.html#gc_parallel. | |||
