Hi, We tried to get
the performance of Libxml (version-2-2.6.23) on a multiprocessor environment,
with two threads running simultaneosly [ Kernel level threads ]. And were expecting
that the performance will scale up, but instead the performance recorded is almost
similar [3% more] to what we get for single thread. Each thread parses
the xml document using xmlSAXUserParserMemory. Can anyone help me
to identify the root cause for this?? I surmise that
this may be because of the extensive locking of Data and/or Api's done inside Libxml. Do we have any
data for multithreaded performance on a multiprocessor system?? Also, can anyone tell
that to what extent the performance of Libxml is expected to scale up on a multiprocessor
environment. Thanks in advance !! Regards, Harbhanu |
