Re: [perf-discuss] Performance problem with nrand48()

This appears to be the implementation: http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libc/port/gen/drand48.c In that code, it looks to me like nrand48() locks the mutex and then calls _nrand48_u(), an internal function. The _nrand48_u() function saves the global data, copi
