Hi all,
my RT 4.0.2 installation is too CPU hungry, expecially for apache2
threads. Here’s the HTOP display of processes and threads:
Page reponse was very slow and RT is not so usable 
My RT work under SSL and this is apache2’s config:
ServerAdmin webmaster@tickets.unisi.itDocumentRoot "/opt/rt4/share/html"
<Location />
Order allow,deny
Allow from all
SetHandler perl-script
PerlResponseHandler Plack::Handler::Apache2
PerlSetVar psgi_app /opt/rt4/sbin/rt-server
</Location>
<Perl>
use Plack::Handler::Apache2;
Plack::Handler::Apache2->preload("/opt/rt4/sbin/rt-server");
</Perl>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/ssl_access.log combined
SSLEngine on
...
BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
And this is my RT_SiteConfig.pm:
root@tickets:/opt/rt4/etc# cat RT_SiteConfig.pm
Set($rtname, ‘tickets.unisi.it’);
Set($WebDomain, ‘tickets.unisi.it’);
Set($Organization, “unisi.it”);

RT::Authen::ExternalAuth)));
Set($LogToFile, 1);
Set($LogDir, q{var/log});

Set($ExternalAuthPriority, [ ‘My_LDAP’ ]);
Set($ExternalInfoPriority, [ ‘My_LDAP’ ]);
Set($ExternalServiceUsesSSLorTLS, 0);
Set($AutoCreateNonExternalUsers, 1);
Set($ExternalSettings, {
‘My_LDAP’ => {

‘server’ => ‘[ldap server]’,
SERVICE-SPECIFIC SECTION
# If you can
bind to your LDAP server anonymously you should
# remove the
user and pass config lines, otherwise specify them here:
# The username
RT should use to connect to the LDAP server
‘user’ => ‘cn=[user],ou=admin,dc=unisi,dc=it’,
# The password
RT should use to connect to the LDAP server
‘pass’ => ‘[pass]’,
# The LDAP
search base
‘base’ => ‘dc=unisi,dc=it’,
# ALL FILTERS
MUST BE VALID LDAP FILTERS ENCASED IN PARENTHESES!
# YOU MUST
SPECIFY A filter AND A d_filter!!
# The filter to
use to match RT-Users
‘filter’ => ‘(objectclass=Unisiperson)’,
# A catch-all
example filter: ‘(objectClass=*)’
# The filter
that will only match disabled users
‘d_filter’ => ‘(objectclass=FooBar)’,
# A catch-none
example d_filter: ‘(objectClass=FooBarBaz)’
# Should we try
to use TLS to encrypt connections?
‘tls’ => 0,
# SSL Version to
provide to Net::SSLeay if using SSL
‘ssl_version’ => 3,
# What other
args should I pass to Net::LDAP->new($host,@args)?
‘net_ldap_args’ => [ version => 3 ],
‘attr_match_list’ => [ ‘uid’,
‘mail’,
‘cn’
],
# The mapping of
RT attributes on to LDAP attributes
‘attr_map’ => { ‘Name’ => ‘uid’,
‘EmailAddress’ => ‘mail’,
‘RealName’ => ‘cn’
}
}
}
);
1;
Any ideas how to speed up ?
