I use hothasktags [1] which works very well. The only problems are sometimes with obscure extensions, where haskell-src-exts (which hothasktags uses) can't parse the file, but that happens very rarely.
Regarding speed: it takes 2-3 s on about 250 source files totaling about 25000 lines on my laptop.
