Can you show me a example where simplefonts is so slow.
Sure, here goes. I should say, most of my documents are 1-5 pages and build time is usually under 5 seconds (2nd and higher runs). One (relatively) slow use of simplefonts is the Chinese example (1) below. The way I pasted it, it runs just under 13 seconds on 2nd and consecutive runs. Not using the adobe but eg the ht series is a whee faster. It's not that I am doing huge amounts of Chinese, but jumping from, say, 3 to 12 seconds, is considerably slower. I was hoping by creating a typescript I could speed things up a bit. Any suggestions welcome. Standing corrected, the impact using eg. CharisSIL for phonetic/IPA symbols the impact is much less: eg. a jump from 2.8 to 4.8 seconds in Example (2) given below. The impact of 2 seconds is bearable! Let me know if you want to see any output or whatever. cheers, Martin %Example (1) \usemodule[simplefonts] \setmainfont[texgyrepagella] \setsansfont[texgyreheros] \setmonofont[texgyrecursor] \setcjkmainfont[adobesongstd] \setcjksansfont[adobeheitistd] \setcjkmonofont[adobefangsongstd] % ttf fonts htsong, hthei, htkai, htfs from: % http://ftp.ctex.org/pub/tex/fonts/truetype/ttf/ %\setcjkmainfont[htsong] % serif, regular %\setcjksansfont[hthei] % sans %\setcjkmonofont[htsong] % mono \setscript[hanzi] \starttext Where there is a will, there is a way. 我命由我不由天 \blank {\rm Serif: 兡也包因沘氓侷柵苗孫孫財 text 兡也包因沘氓侷柵苗孫孫財} %{\ss Sans: 兡也包因沘氓侷柵苗孫孫財 text 兡也包因沘氓侷柵苗孫孫財} %{\tt Mono: 兡也包因沘氓侷柵苗孫孫財 text 兡也包因沘氓侷柵苗孫孫財} \stoptext % Example (2) - Not sure if the IPA symbols post properly... \usemodule[simplefonts] \setmainfont[CharisSIL] \starttext besser [ˈbɛsɐ], der [deːɐ] d͡ʒ \stoptext
