This has languished for a long time, and we should make a decision before FF for 2.15.0. It seems to me that in so far as there is a problem, it is that we serialize via XDR, and that since that was invented little-endian CPUs have taken over the world. So for the only cases I can imagine

[Rd] serialize/unserialize vector improvement

2011-09-28 Thread Michael Spiegel
Hi folks, I've attached a patch to the svn trunk that improves the performance of the serialize/unserialize interface for vector types. The current implementation: a) invokes the R_XDREncode operation for each element of the vector type, and b) uses a switch statement to determine the stream type
