Re: [xml] Need better XML writing performance

Yes, Solaris 6 and higher have excellent i/o performance. 5,000 msgs/sec
does not even begin to tax the system. The app is cpu bound (0% idle). But
thanks for asking!

Just wondering: Can your file system handle 5000 files/sec ?

why not using xmlNewTextWriterFilename  if you write the buffer to a
file anyway? It should also use less memory or a more constant amount
of memory.
