+Quill will probably make the slow scala compiler even slower, since a lot of additional `Parsing`, `Typechecking`, `Implicit resolution` works introduced to expand a Query.
+
+Following tips may help improving compilation time.
+
+## Use `-Yprofile-trace` scalac options.
+With `-Yprofile-trace` option, a chrome trace file will be produced after compilation.
+It will help figure out what slowing down the compiler.
+
+Note, this option need some tweak if you are running on java 9 or newer version.
+
+## Split large module into multiple submodules
+Since scalac is not fully parallelized, split into independent submodules can significantly reduce build time on multi-core cpu.
+
+## Define decoder/encoder directly instead of `MappedEncoding`
+
+`MappedEncoding` introduce more implicit resolutions, which may slow down compiler.
+
+It is possible to define instance directly.
+
+```scala
+case class FooId(id: Long)
+implicit val fooIdEncoder: Encoder[FooId] = mappedEncoder(MappedEncoding[FooId, Long](_.id), longEncoder)
+implicit val fooIdDecoder: Decoder[FooId] = mappedDecoder(MappedEncoding[Long, FooId](FooId(_)), longDecoder)
+```
+
+## Share `QueryMeta` instance
+
+`QueryMeta` generation requires `Decoder` resolution, tree generation, typechecking, etc which can be very slow.
+
+`QueryMeta` is not shared by default, so define shared `QueryMeta` instance may reduce build time.
+
+```scala
+val ctx = SqlMirrorContext(MirrorIdiom, Literal)
+
+// Prevent using default macro generated query meta instance.
+// Use `_` instead of `*` if `-Xsource:3` not enabled.
+import ctx.{ materializeQueryMeta => *, * }
+
+ // Instance type must not be specified here, otherwise it will become dynamic query.
+implicit val orderQueryMeta = ctx.materializeQueryMeta[Order]
+
+ctx.run {
+  query[Order]
+}
+```
+Note, to use [`-Xsource:3`](https://github.com/scala/scala/pull/10439) scalac options, `-Xmigration` or `-Wconf:cat=scala3-migration:w` is required.
+
+Otherwise, it will not compile due to lack of explicit type of implicit definition.
