No. The deserialization of a PCH is handled in a completely independent source code. ASTImporter is responsible to merge two ASTs. These ASTs may come from a PCH - deserialized - , or they may be provided by the parser; from the ASTImporer's point of view this is irrelevant. Thus, there is no performance impact on deserialization of PCHs.
