[Koha-devel] Add Biblio slow

I have contacted the list previously about this issue. We are hosting Koha successfully, but the "add biblio" screen is really a big problem (accessed via the internet). It is impractical to do cataloguing at this speed. It takes 30 seconds on average to start cataloguing a new record. Is there anything to be done to circumvent this issue? The problem is not Javascript related. All other functionality (searches, etc) are satisfactory.
