I doubt there will be a significantly faster solution; sed itself is lightweight and fast. It may be outperformed by a few percent by sth. else, but not orders of magnitude. The task itself is heavy duty: it must compare the data file line by line, char by char, with 10000 to-be-substituted patterns - that will take its time no matter what tool you use.
Be aware that tr can only substitute char by char, not char by word and thus will not solve your problem.

ustrtok
ustrtok(3alleg4) Allegro manual ustrtok(3alleg4)
NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok(char *s, const char *set);
DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be
searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always
copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the
same time). Example:
char *word;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok(temp, " -");
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok(NULL, " -");
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found.
