Re: [Pharo-users] Slow compilation on one of my Windows PCs

#flush on a stream means pushing all data to the final destination, clearing buffers, doing actual network transfers. What can happen when you disable that ? That some data does not arrive where it should I guess. Mind that #close most of the time does an automatic/implicit #flush. Anyway, I don't think disabling #flush is a real solution. > On 02 Jul 2015, at 17:46, Jan BlizniÄenko <bliznjan(a)fit.cvut.cz> wrote: > > I'm experimenting with commenting the flush automatically by startup script > and loading now takes reasonable amount of time ( StandardFileStream > compile: 'flush'. ). > I haven't found any drawbacks so far, but it doesn't mean anything and that > "manual" flushing probably is there for a reason, what is the reason? > > Jan > > > Jan BlizniÄenko wrote >> I tried commenting primFlush: fileID in StandardFileStream>>#flush on my >> desktop PC and the "store" benchmark's speed improved significantly. >> >> Original result on Windows 7: 11 per sec >> Result without flushing on Windows 7: 9 430 per sec >> Original result on Linux Mint 17: 26 590 per sec >> Result without flushing on Linux Mint 17: 34 879 per sec >> >> Mentioned Linux Mint is in VirtualBox on the same PC. >> >> Also loading of Roassal2 now takes 58 seconds insted of 386. >> >> Jan > > > > > > -- > View this message in context: http://forum.world.st/Slow-compilation-on-one-of-my-Windows-PCs-tp4834668p4… > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I'm experimenting with commenting the flush automatically by startup script and loading now takes reasonable amount of time ( StandardFileStream compile: 'flush'. ). I haven't found any drawbacks so far, but it doesn't mean anything and that "manual" flushing probably is there for a reason, what is the reason?

Hi Jannik, about that. Why is Phratch not picking the language from the environment? Scratch on the same platform (linux / french) does it.

Dear Offray, Thank you for using phratch. Spanish is available. You just have to click on the sphere on the left of "file" menu. Here, you will find a list of available languages. Sometimes, there are blocks that are not translated. In this case, don't hesitate to contact me, we will translate them.
