The other day I was building our new orders interface in VueJS and I came across a performance problem on large orders where we were creating a large number of Hibernate objects in one request. For 750 objects the request was taking around 2 minutes. This was certainly unacceptable as the whole reason I was building a new orders interface was to scale better and provide a better UX. So I started looking at options to do a batch insert instead, unfortunately we are stuck on Hibernate 2 at the moment due to a rather large code base that cannot be easily upgraded.
