[Koha] Koha Performance

Hi, i'm new to Koha and at the university i'm working at we have a small library with about 50 items. We have a small server where Koha is running on. Plack is also enabled. We are running a Mariadb on an other server. The problem is, that it takes about 10 seconds for a request to be answered. In example a User is searching for "Alters-Konzentrations-Test" and the result takes about 10 seconds. Also the whole navigation on the page feels slow. Per search request there are about 4000 queries sent to the database server, is this normal? What else can I check?
