[gentoo-user] Acroread 7.0.5-r1 very slow startup

[gentoo-user] Acroread 7.0.5-r1 very slow startup

[Urs Schuetz]

Acroread startup is very slow on my gentoo sistem. It takes more
than 2 minutes to start acrobat on my old AMD Duron 800 MHz. Also
on further startups the load time stays more or less the same.

The CPU is 100% used during most of the startup period, which is
strange. Top shows CPU usage of 75-98% for acroread during
startup.

I have this long startup time only since upgrade to version
7.0.5-r1. The older version 7.0.1.1 loaded within 15 seconds
first load, and within 5 seconds on further loads.

ldd /opt/Acrobat7/Reader/intellinux/bin/acroread showed a problem
with the library path. So I added
/opt/Acrobat7/Reader/intellinux/lib to LD_LIBRARY_PATH.

I also moved plugins in 
/opt/Acrobat7/Reader/intellinux/plug_in
to 
/opt/Acrobat7/Reader/intellinux/plug_in_DO_NOT_LOAD_THEM, 
and moved 
/opt/Acrobat7/Reader/intellinux/SPPlugins/ADMPlugin.apl 
to
/opt/Acrobat7/Reader/intellinux/plug_in_DO_NOT_LOAD_THEM.

But the startup time on version 7.0.5-r1 of acrobat reader is
still more than 2 minutes.

strace acroread
shows that acroread 7.0.5-r1 uses a very long time with fonts
and nonexistent directories like /usr/psres and
/usr/share/fonts/afms//usr/share/fonts/afms:

...
 open("/usr/X11R6/lib/X11/fonts/Type1/fences.ttf", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = -1 ENOTDIR (Not a directory)
 open("/usr/X11R6/lib/X11/fonts/Type1/l048013t.pfa", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = -1 ENOTDIR (Not a directory)
 getdents64(5, /* 0 entries */, 4096)    = 0
 close(5)                                = 0
...

and "hangs" here for about 10 seconds, with CPU 100% used. This
happens nine times during startup.

I don't see any network activity during startup of acroread
(blocked with:
iptables -A OUTPUT -o eth0 -p tcp -m owner --cmd-owner acroread -j REJECT --reject-with tcp-reset)

Sorry for the long lines.

Can anybody conirm this slow startup, or is it just me? Any hints
how to speed up acrobat reader 7.0.5-r1?

I can. It takes ~40 second at P4 2.4. Acroread isn't open source,
so, instead of filing any bug, I switched to kpdf :-)

I can confirm. It took two and a half minutes now on my box (P4 2GHz,
512M ram). It does feel slower than the older version.

I noticed the same thing.  There is a bug open about it on
bugs.gentoo.org I believe, but the workaround for now is:

mv ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst ~/.adobe/Acrobat/7.0/Cache/UnixFnt.old
touch ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst

That worked for me atleast.

Works for me too.  Thanks Mark.

I can confirm the same behavior on my system.  800 MHz hyperthreaded P4, 
and top shows that one of the cores hits 100% while acroread is starting 
up.  It takes nearly three minutes to load, and strace shows it hanging 
at the same places.  I'll probably go back to 7.0.1.1.

from the forums:

http://forums.gentoo.org//viewtopic-t-420754-highlight-acroread.html?sid=5118566558bdce7510b095567e7b6d4c

the file ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst stores a list of all
the fonts on your system (which, in my case, gives 9387 entries) and
apparently it tries to open those one by one on startup and look
inside (what for, I don't know). 

A temporary work around is provide in the link above, which amounts to
removing that font file prior to starting acroread. If I do that,
acroread starts under 5 seconds for every one of the five times I
tried. 

Notice that /usr/bin/acroread is just a batch file to launch the
executable, so if you are adventurous, you can go dig inside it a bit.

Thanks for the forums link, and the other hints! The following
ideas from the forum solved the slow startup:

as user:
rm ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst
ln -s /dev/null ~/.adobe/Acrobat/7.0/Cache/UnixFnt07.lst

and as root:
cd /usr/share/fonts
chmod 750 100dpi 75dpi cyrillic misc ukr

(I did not test this for side effects yet, try at your own risk!)

Now the acroread startup times are back to normal. It helps to
remove unused plugins in /opt/Acrobat7/Reader/intellinux/plug_ins
