https://www.delphitools.info/2013/11/05/multi-threaded-string-building-in-delphi/
    Multi-Threaded String Building in Delphi
TStringBuilder
    StringBuilder is the RTL’s TStringBuilder class
    Trivial is using plain String concatenation with the “:=” and “+” operators
TTextWriter    
    TTextWriter is the mORMot/Synopse class (it’s the only one operating in utf-8)
TWriteOnlyBlockStream    
    TWriteOnlyBlockStream is the DWScript class from dwsUtils
    StringBuilder and Trivial cases only use one CPU, their bottlenecks are the RTL functions for String reference counting and the memory manager (Delphi-side).
    TTextWriter and TWriteOnlyBlockStream bottlenecks are found in the concatenations, integer-to-string conversions, and VirtualAlloc calls to Windows.
