| coldpress | moritz: it's the same as part 1, but instead of finding the 2020th number, you find the 30000000th number | 08:10 | |
| i'm now thinking of having an array for the lower-valued numbers, and a hashmapfor the higher-valued numbers | |||
| moritz | can't you just have a hash that is indexed by number and the value is the last occurance index? | 08:12 | |
| or is that too slow? | |||

| coldpress | that takes 1.6++hours | 08:44 | |
| numbers said are distributed logarithmically, so lower numbers are said very often | 08:45 | ||
| hashing an integer 30000000 times is not ideal | |||
| alright, can confirm that using an array for the lower 300 numbers gives a user time of 24min and sys time of 18min | 08:51 | ||
| timotimo | huh that is a really big amount of sys time. it doesn't do a lot of swapping or anything, does it? | 08:52 | |
| MasterDuke | m: my %h; %h{$_}++ for ^1_000_000; say now - INIT now; say %h.elems; | ||
| camelia | 3.4712895 1000000 |
08:53 | |
| MasterDuke | m: my Int %h; %h{$_}++ for ^1_000_000; say now - INIT now; say %h.elems; | ||
| camelia | 3.4336643 1000000 |
||
| MasterDuke | huh. locally i get a consistent difference of 0.4s slower for the Int hash | 08:54 | |
| coldpress | m: my Int %h; %h{$_}++ for ^30_000_000; say now - INIT now; say %h.elems; | 08:56 | |
| camelia | (timeout) | ||
| coldpress | I think big hashmaps take more time | ||
| because not enough buckets or something like that | 08:57 | ||
| well I guess not all 30_000_000 numbers are actually hashed | |||
| should be more like 10_000_000 | 08:58 | ||
| m: my Int %h; %h{$_}++ for ^10_000_000; say now - INIT now; say %h.elems; | |||
| camelia | (timeout) | ||
| MasterDuke | spends almost all the cpu time in MVMHash_gc_mark | 09:03 | |
| non-linear. locally. 1m entries takes 2.5s, but 10m took 83s | 09:04 | ||

| MasterDuke | for 10m it's 5s quicker when it's not typed. i.e., 83s for Int, 78s for normal | 09:44 | |
| timotimo | ah, dang. possibly because stringifying an Int is slightly less work than putting the class name in front | 09:45 | |

| this is just a golfed typo (== instead of ~~), error struck me as lta | 17:59 | ||
| but to your point, i guess it's just a less golfed use of == instead of eq | 18:00 | ||
