edje_cc has 2 new options. -fastcomp and -fastdecomp. -fastcomp uses lz4. -fastdecomp uses lz4hc. fastcomp is fast to compress and decompress, but edje files bloat up by about 50% bigger (as expected). but compression time is faster than zlib and fastdecomp. fastdecomp is slower to compress than zlib, with the same compression ratios, but is faster to decompress at runtime. so it's a tradeoff as with many things. the only places you can really measure this is things like startup time of e or apps when they have to load and decompress edje data into memory, especially if the3 data is already cached in ram in the kernel buffer/cache. you may fine we save a few ms. feel free to find a way to test this. :) (e17 has some debug output of its own to give you timings of startup - this gets dumped to stdout. other apps - u'd have to add instrumentation somewhere to basically time how long between the beginning of main() and when the mainloop finally goes idle) > Rgds > -----Message d'origine----- > From: Carsten Haitzler (The Rasterman) > Sent: Monday, May 21, 2012 1:37 PM > To: Enlightenment developer list > Cc: Thomas Kueling > Subject: Re: [E-devel] using LZ4 compression tool in eet ? > > On Sun, 13 May 2012 18:27:05 +0000 (UTC) Thomas Kueling > <thomas.kuel...@gmail.com> said: > > > > Torri <vincent.torri <at> gmail.com> said: > > > > > > actually forget lz4hc... lgpl3. > > > > > > > Well, apparently no longer : > > LZ4 HC just went BSD. > > > > http://code.google.com/p/lz4/ > > eet now supports both lz4 and lz4hc :) in svn only tho. > > -- > ------------- Codito, ergo sum - "I code, therefore I am" -------------- > The Rasterman (Carsten Haitzler) ras...@rasterman.com > -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
