@Guillaume : I just uploaded Google Perftools 1.4 for Lenny, I did edit the corresponding how-to (http://www.dotdeb.org/2008/08/25/using-the-google-perftools-to-speed-up-your-mysql-server/) and I’ll make an announce about it.

Thanks for this upgrade request.

Hi there,
Google Perftools 1.4 has been released, what about an update on dotdeb, so we’ll see if we can use it with mySQL!
thanks a lot Guillaume for your great work.

Hi,

I also had the problem with version 1.3 and MySQL on Etch (segmentation fault). So I downloaded version 0.98 and then everything went fine. Here ist the link where I downloaded it (I searched a long time for it, so that’s why I post it here): http://archives.dotdeb.org/dists/etch/google-perftools/0.98/binary-i386/

I don’t know if it’s really faster, is there a way to test it (not subjective) if it’s really faster? Memory consumption should be the same, yes?

@Daniel : Google Perftools 1.3 seem to have a problem and crash MySQL. Many users reported this. I’m rolling back to 1.0. Please desactivate them.

Thank you, this fixed one error but a new one is showing up:

Starting MySQL database server: mysqld/etc/init.d/mysql: line 108: 1377 Segmentation fault /usr/bin/mysqld_safe >/dev/null 2>&1

Maybe the same error the others reporting.
The perftools-version before this update was working.

@Daniel : you have to uninstall libtcmalloc-minimal0 before upgrading libgoogle-perftools0.

Hi,
this error is thrown on upgrading perftools in my debian etch, so upgrading fails:

#apt-get uprade
…

I removed perftools until I can use it again.

when I stop mysql before adding line

export LD_PRELOAD=”/usr/lib/libtcmalloc.so.0″

to /etc/init.d/mysql I get different error:

# /etc/init.d/mysql start
Starting MySQL database server: mysqld/etc/init.d/mysql: line 110: 16797 Segmentation fault /usr/bin/mysqld_safe > /dev/null 2>&1
