| timotimo | a little profile of hello world on perl6-m shows it spends 6.4% in interp_run, 6.1% in reentrantmutex_lock, 4.3% in reentrantmutex_unlock | 09:24 | |
| 3.8% in string_utf8_decodeand 3.3% in serialization_read_ref | |||
| well, a perf profile - meaning it's probabilistic | 09:26 | ||
| but still ... | |||
| curious result IMO | |||
| JimmyZ | I have a basic AA, but I don't know how to get it used :( | 09:29 | |
| the problem is that I don't do AA between different ins and blocks | 09:30 | ||
| *don't know how to do | |||
| timotimo | "differens ins"? | 09:31 | |
| anyway, i'll be AFK for a bit | |||
| JimmyZ | luajit is by chain | 09:32 | |
| timotimo | maybe a little preprocessor would be interesting that creates C initializer literals or whatever for string constants that we decode from utf8 at run-time at some point | ||

| japhb | timotimo: Did your profile show where those heavy routines were being called *from*? | 16:51 | |
| TimToady | I think they were being called from somewhere in Europe... | 16:55 | |
| FROGGS_ | >.< | 17:04 | |
| if it starts with 555 you know it is a fake | 17:05 | ||
| japhb | Well, mostly: en.wikipedia.org/wiki/555_%28telephone_number%29 | 17:21 | |
| It turns out that not all 555 numbers are fake. I had to deal with that when I wrote a telecom billing system. :-) | 17:22 | ||
| TimToady | gotta watch out for those fake fakes... | 17:27 | |
| japhb | You would not believe the uproar if you misbill by even a penny -- and fake numbers are expected to be zero cost -- *even if the phone switch routes them somewhere successfully* | 17:29 | |
| There are also weird cases like islands changing national identity, areas switching between national and international dialing, and more. It's a deep rabbit hole if you want to get it right and not just punt the hard cases over to customer support .... | 17:32 | ||
| timotimo | japhb: perf has some trouble correctly getting the call graphs | 17:36 | |
| japhb | timotimo: Ah, too bad. Would be nice to know what's doing so much locking. (It would be even nicer to know if that locking was contended.) | 17:44 | |
