Hi :)
I was wondering it there is likely to be a slow-down in opening or
normal usage when there are a lot of languages installed.


"tk" below says that RAM usage of LO grows as languages used increases.

I think it's generally true. But I would like to offer my opinion, although
I haven't dambled in developing LO at all.

If no additional language packs are used, RAM increase would be trivial, as
the application simply allocates a new data structure to store the scripts
from the new languages. I don't see why memory store for Asian text or
complex script should be so much larger than typical western texts as to eat
up RAM this quick. This is not simply a byte calculation. Different
languages have different entropy values.

But to be more precise, if a new language you introduce in to the document
involves activation of text processing not required by the languages already
used in the doc, extra memory is needed for this job. For example, you begin
typing in some Chinese characters in a language already with English,
Spanish, French and German texts. Chinese is Asian text and has its own
processing rules, and LO has to turn on Asian text typography to support
hadling of Asian texts. This may involve loading a series of libraries,
which is not likely to happen if you type some Swedish instead. Similary, if
you then type in some Arabic then the bi-directional processing libraries
would also have to be loaded to support complex scripts, which is not likely
to happen if you type some Norwegian instead.

"雷聲 靐䨻": if you can see four Chinese characters instead of blobs or question marks than your 
browser/OS has a good support for Unicode and CJK characters! (P.S. the four chracters put together 
means "loud thunder")
