Description Jérôme 2013-09-08 19:05:43 UTC
Problem description: 

Most office computers now have at least 2 cores. However, the documents open slowly even if the quick start is enabled.

Steps to reproduce:
1. open any lo document

Current behavior:
Currently, it seems there is only 1 process which is opening the document. As a comparaison Microsoft Office documents open faster (although they are not for the same purpose).

Expected behavior:
I think we could use 2 processes. One process would read the archive file and extracts the content into a shared memory. The second process could read a file once its first bytes are available into the shared memory. It would look like a Posix pipe for each file of the archive.

Operating System: Linux (Other)
Version: Inherited From OOo
Last worked in: rc

Smells like an enhancement request, not a regression.

Here are some discussions re: multi-thread/multi-processor work:
