+### When I run snap with multiple cores, throughput plummets. What's going on?
+
+The parallel GC introduced in GHC 6.10 doesn't seem to play very well with
+Snap. If you turn parallel GC off (using the "`-qg`" flag, e.g. "`./foo-website
++RTS -N -qg`") throughput should improve dramatically.
+
+
+### How can I get debugging output?
+
+With recent (>0.2.12) snap-core, if you set the environment variable `DEBUG=1`
+then Snap will produce debugging output to stderr. There is a *very* slight
+performance penalty associated with this feature; if you are in a production
+setting and require speed at all costs, you can disable debug output when
+building `snap-core` by passing the `no-debug` flag to `cabal install`:
+
+~~~~~~~~ {.shell}
+$ cabal install snap-core -fno-debug
+~~~~~~~~
+
+
### How can I help?
##### Use Snap to build real websites.
