php - Speed up forum conversion -

-

i'm converting forum mybb ipboard (the conversion done through php script), have on 4 million posts need converted, , take 10 hours @ current rate. have unlimited ram , cpu, want know how can speed process up? there way can allocate huge amount of memory 1 process? help!

you're not going script run faster. giving more memory, might able have more posts @ 1 time, though. change memory_limit in php.ini file change how memory can use.

you might able tell script 1 forum @ time. run several copies of script @ once. limited how talks database table , whether script has been written allow -- might daft things lock target table or insanely long read on source table. in case, unlikely more 3 or 4 running @ once without slowing down, anyway.

it might possible improve script, several days' hard work learning insides of both forums' database formats. have asked on forums ipboard? maybe there has experience @ you're trying do.

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
