The units StrPosDefs and StrPos32 and/or StrPos64 contain functions that extend the functionality of system.pos and sysUtils.StringReplace and they may lead to significant performance improvements.
Functionality:
• (repeated) location of substring in a string, (ANSIstring or String) with or without case sensitivity.
• Replacement of a pattern by another pattern in a string or ANSIstring (one or all, with or without case sensitivity)
Platforms:
• 32 and 64 bit windows.
Speed:
• string replacement can be 6-9 times faster than standard.
String search gain primarily in 64 bit mode (40% faster with string, 10x faster with ANSIstring).
Features
- Fast StringReplace (both 32 and 64 bit)
- Fast Pos (primarily 64 bit)

Good idea but : 1/ Not easy to dowload the all project : you need to dowload every file. 2/ Not clear to see the targeted Delphi versions : in D 10.3 I can't use it without crash.Reply from Delphi fast Pos & StringReplacePosted 2022-03-03
It was developed in 10.3 and tested in XE4 and XE5. It would be very useful to know the circumstances under which you get a crash. If you can send code I will analyse. My email is in the documentation.
