I've noticed FF 3.0.1 (on solaris10 amd64) stalling at times, while I was viewing mathml documents at http://pear.math.pitt.edu/mathzilla/ (look for sample mathml documents there, eg., see "http://pear.math.pitt.edu/mathzilla/Examples/markupOftheWeek.mhtml";). After I did a
truss -fvall -p FFpid I saw that it kept checking all of my font files every once a while. I do have 2295 fonts installed (most from LaTex 'texlive' distribution) so that was taking some time (1-3min). See bellow excerpt: ..... 20891/1: xstat(2, "/usr/local/texlive/2007/texmf-dist/fonts/vf/cspsfonts-adobe/zapfchan", 0x0803D280) = 0 20891/1: d=0x01980044 i=161341 m=0040755 l=2 u=0 g=0 sz=512 20891/1: at = Apr 22 13:16:02 CDT 2008 [ 1208888162 ] 20891/1: mt = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: ct = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: bsz=8192 blks=2 fs=ufs 20891/1: xstat(2, "/usr/local/texlive/2007/texmf-dist/fonts/vf/ibm/timesnew", 0x0803D280) = 0 20891/1: d=0x01980044 i=161344 m=0040755 l=2 u=0 g=0 sz=1024 20891/1: at = Apr 22 13:16:02 CDT 2008 [ 1208888162 ] 20891/1: mt = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: ct = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: bsz=8192 blks=2 fs=ufs 20891/1: xstat(2, "/usr/local/texlive/2007/texmf-dist/fonts/vf/monotype/helvetic", 0x0803D280) = 0 20891/1: d=0x01980044 i=161368 m=0040755 l=2 u=0 g=0 sz=512 20891/1: at = Apr 22 13:16:02 CDT 2008 [ 1208888162 ] 20891/1: mt = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: ct = Apr 17 13:06:03 CDT 2008 [ 1208455563 ] 20891/1: bsz=8192 blks=2 fs=ufs 20891/1: xstat(2, "/usr/local/texlive/2007/texmf-dist/fonts/vf/monotype/timesnew", 0x0803D280) = ..... I believe that checking the same collection of font files is wasteful and it should be only when really necessary. BTW: KUDOS to FF team on Solaris that now it can use correctly mathml related fonts in the browser. thanks This message posted from opensolaris.org
