I understand and agree: RCU must prove itself -in- -Linux-. >The last time I looked, Solaris and AIX and all the rest of the "scalable" >systems were absolute pigs on smaller hardware, and the "scalability" in >them often translates into "we scale linearly to many CPU's by being >really bad even on one". Again understood and agreed. Simplicity and single-CPU performance are at least as important as scalability. Although I believe that RCU can be an important part of all three in some situations, this belief is clearly in need of more proof.
