Florian Schmaus 6322f4f826 [core] Add global option to flatten when appending in XmlStringBuilder ... For certain use cases, this provides a performance improvement, probably due better cache locality. However, it comes with the cost of additional memory consumption. This was initially suggested by Boris Grozev, who also reported a significant performance problem of XmlStringBuilder/LazyStringBuilder. However, the main cause of the performance probelm was the missing caching of LazyStringBuilder. The length of the lazy string is now cached by LazyStringBuidler since 70e48300a6 ("[core] Cache length in LazyStringBuilder"), which accounts for large performance improvement. A significantly smaller improvement is achieved by this commit and setting XmlStringBuilder.FLAT_APPEND to 'true'. Suggested-by: Boris Grozev <boris@jitsi.org>		2023-11-26 21:34:13 +01:00
