Small. The total size of code plus data is less than 20 KB (IA32). - * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866 - * takes only 3.9 seconds. - * 3. No memory allocation. It uses a static object. No need to initialize or - * cleanup. - * 4. Thread safe. - * 5. Support embedded architectures that has no misaligned memory access - * support. - * - * Limitations: - * - * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU. - * If a Setup signal contains more than 30 faststart, the packet size will - * very likely exceed the MTU size, then the TPKT will be fragmented. I - * don't know how to handle this in a Netfilter module. Anybody can help? - * Although I think 30 is enough for most of the cases. - * 2.
