Hi Alex, the profiler report looks rather interesting (thanks so much for
trying all these tools at LibreOffice !). Having said that - its' hard for me
to see where the profiler thinks most of the time has gone ... is there any
%age estimation / call-count or absolute time measurement in there to use ? I
just saw traces.
sberg - IIRC Lionel is fairly convinced this is a Java stack-guard slowness,
and I guess we're hoping to have that ruled out before digging much further. I
believe we fixed that - right ? There is a whole lot of:
1 uno_Environment_invoke (in libuno_cppu.dylib.3) + 37 [0x2d3c7f]
+ ! : | + :
1 uno_Environment_invoke_v (in libuno_cppu.dylib.3) + 28
[0x2d3c58]
+ ! : | + :
1 uno_Environment_enter (in libuno_cppu.dylib.3) + 326
[0x2d3c1c]
+ ! : | + :
1 uno_EnvDcp_getPurpose (in libuno_cppu.dylib.3) +
4215 [0x2d2dee]
+ ! : | + :
1 uno_Environment_invoke (in libuno_cppu.dylib.3)
+ 155 [0x2d3cf5]
+ ! : | + :
1 uno_initEnvironment (in
libaffine_uno_uno.dylib) + 903 [0x1ebdd417]
(assuming the symbols are remotely reasonable).
Is it possible that there is some horrible leak / performance problem /
re-marshalling in the inter-apartment code ?
