I'd just like to note (as is noted in Cap's paper) that the performance data for "Linda" given in the <Parform> paper are actually data for POSYBL (a public domain version of Linda). As a result, these times almost certainly do not reflect the performance achievable with optimized implementations of Linda like those developed by Yale and SCA. Also in the paper: "The bottleneck of LINDA in a distributed environment is the concept of tuple space, especially the necessary scanning operations to find tuples of certain format". Much of the Linda tuple matching is done at compile time (see Nick Carriero's Thesis, Yale University). "Scanning" is not necessary. In addition, modern network Linda systems distribute tuple space eliminating the bottleneck. David
