Some embodiments provide a managed forwarding element (MFE that includes a set of flow tables including a first set of flow entries for processing packets received by the MFE. The MFE includes an aggregate cache including a second set of flow entries for processing packets received by the MFE. Each of the flow entries of the second set is for processing packets of multiple data flows. At least a subset of packet header fields of the packets of the multiple data flows have a same set of packet header field values, and a same set of operations is applied to said packets. The MFE includes an exact-match cache including a third set of flow entries for processing packets received by the MFE. Each of the flow entries of the third set is for processing packets for a single data flow having a unique set of packet header field values.
