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.

Dear all,
We are currently running Koha 3.16.01 and lately noticed sluggish with the software response, including waiting say 10 to 15 seconds for screen to change at times. Last night, I noticed the CPU utilization is running at 100% on Koha instance (Amazon AWS is hosting our Koha) for last few days. Whereas days prior, it would be at under 20%, with spike at rare occasions. No other application being hosted with Koha!
Looking back, our use of Koha hasn't change, except adding a few OPAC User JavaScripts (opacuserjs) to customise the look and feel of our OPAC.
Is the high CPU utilization is caused by adding a few JavaScripts? Or something else altogether??
Hoping someone can help solve this issue.
Kind regards,
