SEP 12RU5 too much concurrent connection

dear guy

after i upgrade SEPM 12RU5 , network team monitor firewall have too much concurrent connection from client to SEPM , all is port 8014 ( see my picture)

what log can i turn off upload from client to SEPM ?  like traffic log , packet log , control log , application  log , clear check box " let client upload critical event immediately" ( i think this is new option in SEPM RU5 was enable by default )....is it good or not ?
