Re: session.save() takes too long

Thiago Monteiro Thu, 29 May 2008 07:48:19 -0700

Hello Stefan,

the insertion itself is fairly straightforward, but the repository structure
might be not. I ran some profile tests to pinpoint where it was slow and the
porblem seems to be on ItemImpl.initVersionHistories. It happens probably
because, for every node inserted, i have to insert some subnodes under it,
some of them versionable, so for every session.save() call, it seems that
createVersion() is invoked many times.


I am copying here my nodetypes.cnd. Also, since i get the data from a DB, to
provide a test case is not really simple, but it is only a loop that creates
the nodes and subnodes (with no documents attached) and, every 250
ctx:registro (the type of node i am inserting) nodes, the session is saved.
The node ctx:registro is inserted under ctx:registros, which is under
ctx:area

For such a structure, should i expect the performance to be so slow? It also
doesn't seem to me that, at least for 300k nodes, the performance degrades
so greatly (about 30% to 40% slower), but should i expect this to happen?

Thanks
