Hi Haipeng

I tried your score on my laptop, running MS Vista, with 2.11.49.  The 
working set was around 127 Mb, and there was no paging.  The original score 
caused Ghostscript to fail due to missing fonts, so I commented out the 
lines which had font-name overrides.  It then compiled successfully and 
produced a pdf of the full score on 3 A3 pages, which looks fine.  It took 
around 2 mins to compile, so about what I would expect.

There are still some minor errors.  The piano change staff causes problems - 
I can't see why.  And four notes have two dynamic markings attached - easily 
fixed.

So try commenting out the fontname overrides - that fixed the problem for 
me - or upgrading to 2.11.49.
