John Polstra c15e7faad5 Performance improvements for the ELF dynamic linker. These ... particularly help programs which load many shared libraries with a lot of relocations. Large C++ programs such as are found in KDE are a prime example. While relocating a shared object, maintain a vector of symbols which have already been looked up, directly indexed by symbol number. Typically, symbols which are referenced by a relocation entry are referenced by many of them. This is the same optimization I made to the a.out dynamic linker in 1995 (rtld.c revision 1.30). Also, compare the first character of a sought-after symbol with its symbol table entry before calling strcmp(). On a PII/400 these changes reduce the start-up time of a typical KDE program from 833 msec (elapsed) to 370 msec. MFC after: 5 days		2001-05-05 23:21:05 +00:00
