We are using Odoo V8 and printing (generating the pdf) Sales/purchase orders, quotations, invoices are quite slower (takes about 3-5minutes sometimes more than that) even with very less records.

But accounting pdf reports are generated within 30seconds and its fine. 

We are accessing a remote server and its a VMware server with a ram of 2GB. I have attached the configuration info in ( https://drive.google.com/open?id=0B9P1jASMRt5GNlNJdzduUmhOeHM&authuser=0  )

What would be the reason for this delay? any suggestion to fix this issue?
