Hi Guys,
I've got some fairly large documents being serialized into various transformers (XSLT, Xinclude and Cinclude.) Every now and then I notice that the stored output is corrupt. Certain elements are in the wrong order etc (I'm using RDF, so for an example I've noticed Description elements out of synch with li elements.) This is happening before I ever get to apply any XSLT. I figure that this could come from the XSPs I'm using (some of which have been converted to generators) or from the X or C include transformations or perhaps a corruption in the store itself (all output is cached very heavily.)
I've been playing with the output buffer settings on the various pipeline types I'm using, and I *think* that this is helping. I suspect that this is going to require a certain amount of contextual configuration - ie: one request will be heavier than another, and thus may require a different buffer size.
My documents are often around the 1 meg mark, so, my question is: does anyone have tips for an appropriate buffer size? I notice *very* odd results if I set the buffer too low: errors show up in included sections of the output etc. If I set the buffer too high, I obviously lose the benefits.
At the moment my buffer size is around 150kb.
What would you suggest as a reasonable number for a 1meg XML document?
Thanks,
Corin
