[Koha] Acquisition module takes more time

I notice in almost every version of the Koha Acquisition module takes usually more time than others especially when entering New purchase suggestion and saving it takes more time. How can I boost this performance? With Regards, Vinod Kumar Mishra, Assistant Librarian, Biju Patnaik Central Library (BPCL), NIT Rourkela, Sundergadh-769008, Odisha, India.
