I have just written:
>There are two O^2 test in the number of tags in C/C++ files which depend on the two options "no-line-directive" and "no-duplicates".  Both options are usable to disable those checks and both are off by default because they help producing a more sane tags file and have no practical impact in most cases.  Both are there because, in principle, they cause significant slowdown in huge tags files.

However, --no-line-directive exhibits the O^2 behaviour inthe number of tags only for languages with the "metafile" property, currently only yacc files.  Unless you have a significant number of yacc files, the impact is O^1 in the number of tag candidates.  And --no-duplicates only matters when creating a ctags file.

Maybe you could give a try and check whether --no-line-directives has any impact
