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

by Jan BlizniÄenko

And one another benchmark of linux in VM on that desktop PC: Roassal loading - 58 s compilations per second - avg: 262.4682, min: 257.194, max: 289.684 ...so the desktop PC is capable of better result and problem is somewhere in Windows, which I was afraid of... I'd also like to add to previous Windows tests that with antivirus turned on everything takes more time approximately by half of original time.

HTTP file logging for Zinc

by Esteban A. Maringolo

Hello everyone, I want to record everything that goes in or out from our REST API servers, maybe including HTTP payload (JSON mostly). ZnLogEvent seems to have the basic building blocks for logging, but I want to know if there is a package/project that already provides file logging, so I can not only have the logs, but also if the file format is compatible with other http logs I can run traditional web log tools on them, like Webalizer or AWStats. Thank you! Esteban A. Maringolo

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

by Peter UhnÃ¡k

I've had also bad results on windows... Windows XP 32bit (VirtualBox) - 178.200 (compilations per second) compared to Ubuntu 32bit (VirtualBox) - 694.932 Debian 64bit (host) - 669.932 I had also had experience with Git handling small files on windows was incredibly slow... so maybe it has something to do with disk writes? What exactly is happening when a method is compiled? A write to changes browser, to the image, parsing, ...?

Chess Game / UpdatingStringMorph

by Volkert

I am trying to load the old chess game from Squeak [1] into Pharo 4.0. The game depends on the class "UpdatingStringMorph", but this is not part of Pharo. What happened to it? Was it renamed? BW, Volkert [1] http://map.squeak.org/package/cb19b6f1-e371-47b2-b814-4bad079d0fbc
