I see this behavior on UbuntuStudio 16.04 LTS using LO 5.1.4.2 (the
distro's standard issue) under one condition. I have an i5-4400
processor running at 3.1 Ghz with 4 cores, and 31 GiB of RAM. I also saw
this with US 14.04 LTS

Delays which appear as a freeze only happen when I open a second
document in Writer. When I open the first one with around 4 MB and some
70 linked images, the doc opens in about 5 seconds. If I then want to
open a second document of a similar size without closing the first, LO
Writer looks like it's frozen, displaying a blank document for up to 30
seconds before suddenly it all comes good.

I've watched the system during this time and 3 of the cores are running
at around 2 or 3% and the 4th core is at 100%.

I have so much RAM that I don't think that can be 'the' limiting factor.
It is more likely that LO can't take advantage of the other cores in the
cpu and is using an insufficient amount of the available RAM.

I see there is an option to change the amount of memory allocated to LO.

for caching graphics objects. Mine was originally set at 100 MB (IIRC)
and I have tried increasing it to 400 MB but this makes no discernible
difference to the delay in loading a second document.

I don't believe I have ever seen a delay / freeze when loading a first
document.
