CPU load highly increased after update

Hello, After the update to Solr 9.7.0, we noticed a CPU load increase of about 50%. This additional load is putting our server under significant stress. Is this issue known, and are there any optimization options available? Any help would be appreciated! Thanks & Regards, Alex K

Error loading class when trying to update

on.SolrException","root-error-class","java.lang.ClassNotFoundException"], "msg":" Error loading class 'solr.extraction.ExtractingRequestHandler'", We modified our solr config a bit, the file is attached. Any idea on how to solve this would be highly appreciated!
