[Koha] Help -- 100% CPU utilization running Koha

[Eric Bégin]

Iming,

Your OPAC doesn't seem to have a robots.txt file.

In that case, webcraler can do multiple requests per seconds, which can 
be hard on your site performance.

Here the robots.txt we are using :

User-agent: *
Disallow:/cgi-bin/koha/opac-search.pl
Disallow:/cgi-bin/koha/opac-export.pl
Disallow:/cgi-bin/koha/opac-showmarc.pl
Disallow:/cgi-bin/koha/opac-ISBDdetail.pl
Disallow:/cgi-bin/koha/opac-MARCdetail.pl

place this file in your koha-tmpl folder.
