Original GitHub issue: https://github.com/netblue30/firejail/issues/1136

Hi there,

more a question than an issue. I have uses ElsterFormular for the German Tax.
It works with and without firejail but in firejail it is unbelievably slow under firejail.
Since I like the idea of wine in firejail it would be interesting if can get a little bit more speed. :-)

I'm not so experienced with wine how are your test and experiences?

Thanks Micha
Below some maybe usefully informations.

@msva commented on GitHub (Mar 9, 2017):

Did you write custom profile for it?
If so, did you enable any trace* directives?
Some apps can start working very slow when run with trace.

If you don't, then:

  1. try to whitelist cache dirs (~/.cache, /var/cache/),
  2. run you app from commandline under firejail with --trace firejail option, and look, which files it trying to access. Sometimes, applications want to, for example, regenerate font cache, if can't find it, and it can take a long time, if you have tons fonts installed. It also can be anything also pretended to be cached.

Hi there,

I use the original from https://github.com/netblue30/firejail/blob/master/etc/wine.profile without a wine.local profile.

maybe it is dedicatet to 32bit:

Parent is shutting down, bye...

I will do some tests and report back.

2:bash:open /dev/tty:3
2:wine:open /usr/bin/wine:3

One process managed to load librace.so. The library is compiled for 64bit systems.

ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/firejail/libtrace.so' from /etc/ld.so.preload cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

This is probably another process. It is expecting a 32bit library. Wine is a combination of 32bit and 64bit processes running in parallel. I don't think --trace will work.

Going back to your original problem: if you run the sandbox with --noprofile, do you still see the slowdown?

starting wine with --noprofile, didn't slowdown wine. But now I'm not sure if I smarter now :-P

I would try to find out what line in the profile is creating the problem: open /etc/firejail/wine.profile and comment out the lines in the profile one by one.

If i comment out seccomp it runs as fast as without firejail.
Maybe dedicated to the switch between 32 and 64bit.
