https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=34141 Bug ID: 34141 Summary: OPAC Search Performance on Ubuntu Server Change sponsored?: --- Product: Koha Version: 22.05 Hardware: All OS: Linux Status: NEW Severity: enhancement Priority: P5 - low Component: Searching Assignee: koha-bugs@lists.koha-community.org Reporter: amar@ourlib.in QA Contact: testopia@bugs.koha-community.org We are experiencing a performance issue with the OPAC search functionality on our server. Despite enabling memcached and Apache2 cache services, the OPAC search is extremely slow and consumes excessive CPU resources, leading to server downtime. Here are the details of our server: - Operating System: Ubuntu 20.04 LTS - CPU: 4 cores - RAM: 8GB - Storage: 200GB SSD When monitoring the server using the 'top' command, we observe that only a few OPAC search requests are being processed. However, these requests are utilizing nearly all of the available CPU resources, leaving no CPU capacity for other tasks and causing the server to go down. It's worth mentioning that we did not utilize the 'koha-common' command for the Koha installation and setup. Instead, we downloaded the Koha tar file and performed the installation using the 'perl Makefile.PL' command. We kindly request your assistance in improving the speed and performance of our server. Any suggestions or guidance on optimizing the OPAC search functionality would be greatly appreciated. Thank you in advance for your support.
