Good Morning, In the version of Koha 20.05.02 with Ubuntu 20.04. I was seeing a slow process. I verified with the TOP command an excess of CPU usage that was causing Koha to slow down. I carried out the following instruction and the slowness was resolved. cd /usr/share/koha/opac/htdocs sudo nano robots.txt Crawl-delay: 60 User-agent: * Disallow: / User-agent: Googlebot Disallow: /cgi-bin/koha/opac-search.pl Disallow: /cgi-bin/koha/opac-showmarc.pl Disallow: /cgi-bin/koha/opac-detailprint.pl Disallow: /cgi-bin/koha/opac-ISBDdetail.pl Disallow: /cgi-bin/koha/opac-MARCdetail.pl Disallow: /cgi-bin/koha/opac-reserve.pl Disallow: /cgi-bin/koha/opac-export.pl Disallow: /cgi-bin/koha/opac-detail.pl Disallow: /cgi-bin/koha/opac-authoritiesdetail.pl The question is, does this instruction completely limit the indexing of the google robot or partially limit it? Thank you, Victor
