Reducing fontconfig system calls

I'm running fontconfig in a sandbox, using ptrace, so each system call by
fontconfig has a great cost. Some of these come from file opening, and
numerous small file reads.
Has anyone looked into reducing system calls and small file reads? Is there
a way to configure fontconfig to minimize small reads? Would I need to
modify the code? If so, which areas should I be looking at?
Also, I'm not using a font cache, and I'm not sure how it works. Does it
have any bearing on this problem?
