And, of course, interpreted expressions execute much slower than compiled expressions and, because the interpreted expression is single-threaded through the host, your program will experience network latency delays in addition to waiting for the host to process the request. The following table shows the performance of interpreted and compiled expressions on Compaq Tru64 UNIX, IBM AIX, and SGI IRIX platforms. A single-threaded test program used a simple loop with 15,000 iterations. An evaluation point containing a function call was placed inside the loop. The numbers shown show the mean and median intervals between consecutive occurrences of the evaluation point.
All times represent the number of seconds needed to execute one evaluation point.
Also, median time to execute the compiled expression on the Alpha was less than one clock tick. All rights reserved.
