I would also like to learn more about where the bottleneck is.

Could you do the following:

M-: (require 'gdb-mi) RET
M-: (defun gdb-get-source-file-list () nil) RET

then run M-x gdb as usual, and see if that makes any difference in
performance?  Leave gdb-create-source-file-list set at t.

(The above steps cause gdb-mi to issue the -file-list-exec-source-files
command and read the output, as usual, but skip parsing the output into
the source file list.)
