Summary: 3.0.8 Very Slow Compared to 3.0.6 (on Gentoo Linux)

Initial Comment:
I was using privoxy 3.0.6 for a long time with no noticeable performance hit.  I \
switched to 3.0.8 and opening multiple tabs in Firefox (as I always did) takes \
literally ten times longer.  I disabled all firefox extensions and compared using \
privoxy 3.0.8 to "direct internet connection" and again saw the massive slow-down \
when using privoxy.  (I do NOT have 'single-threaded' turned on.)

Gentoo linux (Gentoo Base System release 1.12.11.1) using Linux kernel 2.6.25.8  (The \
standard kernel.org kernel, not a gentoo kernel.) X86_64 (64-bit)

Firefox 2.0.0.14   64-bit

NOT using TOR

I have the following debug lines set and see no messages when browsing:

debug   4096 # Startup banner and warnings
debug   8192 # Non-fatal errors
debug   4    # I/O status


If I should run with additional debug flags or can provide more information, config \
file, etc,  please ask.

Thanks for getting back to us.

Now that you mention it, I also see that your
configure output contained the --disable-pthread
switch which is almost always a mistake (for Privoxy).

You also might want to report this to the maintainer
of the Gentoo package, just in case he isn't aware
of the problem.

The 'proper' fix.

The real problem is that I didn't have my gentoo 'threads' use flag set. 
So by adding 'threads' to the USE variable in /etc/make.conf  OR adding a
line just for privoxy in /etc/portage/package.use   then re-emerging
privoxy: I get a fast privoxy 3.0.8

[SOLVED]

The issue seems to be caused by the gentoo patching of the privoxy source
during a gentoo 'emerge privoxy'  (Thanks for asking about the gentoo
patches, that put me on track for a fix.)

Here is a summary of the problem and how I fixed it on my Gentoo system:


Privoxy 3.0.8 slow on a gentoo system:

Connections via privoxy 3.0.8 were very slow. (3.0.6 did not have this
issue.)
The gentoo patches (added during "emerge privoxy") seem to be the culprit.
 To  
fix on a gentoo system, assuming privoxy 3.0.8 is already emerged:

Compile privoxy by hand according to  the installation instructions
provided
in the privoxy source code.  Do NOT 'make install'.  Instead after you
'make' just
copy the resulting privoxy binary over the emerged one at
/usr/sbin/privoxy
Then restart privoxy.   (/etc/init.d/privoxy start)

Note:  you should be able to find the source at: 
 /usr/portage/distfiles/privoxy-3.0.8-stable-src.tar.gz
 on your system.

Thanks for the quick reply.

I'll try 3.0.9 beta tomorrow.

One more piece of information.  I took the config file I was using with
privoxy 3.0.6 and after changing 'standard' to 'standard.action' etc.  I
ran 3.0.8 with my 3.0.6 config file ... same result: SLOW browsing.

I am using the gentoo patches that I receive when I install using:
"emerge privoxy"

I think I'll also try compiling privoxy 3.0.8 by hand without any gentoo
patch and see if there is any difference.  (configure; make)

Here are the lines in my config file that are not comments:

Thanks for the report.

Are you using vanilla sources or Gentoo-specific patches?
What does the configure output look like?

Can your reproduce the problem with 3.0.9 beta?
It's not officially released because the upload
server has been unavailable for the last days,
but you can get if from CVS or at:
http://www.fabiankeil.de/sourcecode/privoxy/privoxy-3.0.9-beta-src.tar.gz
http://www.fabiankeil.de/sourcecode/privoxy/privoxy-3.0.9-beta-src.tar.gz.asc

You aren't the first Gentoo user with this problem,
there's also:

 which got automatically closed due to lack of feedback.
