| lizmat | I thought "use" would actually mmap precomps? probably should ask on #moarvm | 08:13 | |||||||||||||||||||||||||||||||||||||
| nine | What would be the benefit of such a cache? We load (mmap) each precomp file once at most. | 09:24 | |||||||||||||||||||||||||||||||||||||

| Xliff | P6-GLib suite timing statistics for Raku 2022.07.90.g.5.e.1.f.092.f.5 | 17:08 | |||||||||||||||||||||||||||||||||||||
| Total number of projects: 33 (502148 loc) | |||||||||||||||||||||||||||||||||||||||
| Total non-parallel compile times: 8672.000 (262.788 avg) | |||||||||||||||||||||||||||||||||||||||
| Total parallel compile times: 1307.643 (39.626 avg) 6.632x speedup | |||||||||||||||||||||||||||||||||||||||
| nine: I was thinking the cache would be persistent across executions of raku. | 17:20 | ||||||||||||||||||||||||||||||||||||||
| So mmap once, keep for as long as the daemon stays resident | |||||||||||||||||||||||||||||||||||||||
| However, now that I think about it, that might require a non-insignificant, and non-significant amount of change to moarvm. | 17:21 | ||||||||||||||||||||||||||||||||||||||
| Is it possible to check how long it takes to load a set of precomp files from disk, and then the times it takes to mmap them? | 17:22 | ||||||||||||||||||||||||||||||||||||||
| Should be several orders of magnitude. Multiply that by hours of raku use. | |||||||||||||||||||||||||||||||||||||||
| The time saved should be significant. | |||||||||||||||||||||||||||||||||||||||
