Can I use the CDS with tuplescope to do performance fine-tuning?
Not really. There are two major problems in trying to determine performance with CDS tuplescope. First, tuplescope has a large impact on performance, since each tuple operation incurs a lot of X windows support overhead. This overhead swamps the cost of the Linda operations. Secondly, the very nature of the CDS makes it hard to draw conclusions about performance, since the CDS timeshares several concurrent processes on a single CPU (see 7.7 for a discussion of the CDS implementation). Parallel performance tuning cannot generally be done in this context. For performance tuning in Network Linda, we recommend using the Paragraph profiling tool.
