Thanks David. Does anyone happen to know why the memory allocation libraries in Solaris are so much slower than their Linux counterparts? If the various malloc implementations were a second or two slower, I could understand. But they appear to be 10 - 12 seconds slower in our specific test case, which seems kinda odd.
