Scripting Performance Test Bed Details

Setup

1. Downloaded the following:
   Tcl7.6 Tcl8.0
   TclBlend1.0b1up1
   JDK1.1.5
   Jacl1.0b1 prebuilt .class files.

   Tcl7.6 was configured with:

   configure -prefix=/vol/wang/wang2/pt/cxh/tcl7 --enable-gcc -enable-shared
   

   Tcl8.0 was configured with:

   configure -prefix=/vol/wang/wang2/pt/cxh/tcl --enable-gcc -enable-shared
   

   TclBlend was configured with

   ./configure --with-java=/vol/wang/wang2/pt/cxh/jdk1.1.5 --prefix=/vol/wang/wang2/pt/cxh/tclblend
   

2. Compiled the above software with gcc 2.7.2.2.
3. Installed the above software on a local partition of a Sun Ultrasparc 200 with 256Mb of memory running Solaris2.5.1.
4. Downloaded Kernighan's source and datafiles from http://cm.bell-labs.com/cm/cs/who/bwk/timingtests.tar.gz and http://cm.bell-labs.com/cm/cs/who/bwk/timingdata.tar.gz
5. Jacl has problems with gets. It appears that gets returns 0 when the end of file is reached instead of returning -1. The fix was to edit the tcl sources for the tail, wc and sum1 tests and change the >= to >:

   	while {[gets $fd line] >= 0} {
   

   became

   	while {[gets $fd line] > 0} {
   

6. Jacl does not have fconfigure, so the cat and tail Tcl tests need the fconfigure wrapped in a catch:

   catch {fconfigure stdout -buffering full}	;# not needed on unix
   

7. Edited the makefile appropriately.
8. Ran make jclass to compile the Java tests used by Java and Tcl Blend.
9. Ran make p.plt to create p.plt. This took a very long time, some of the Jacl tests take 30 minutes to run.
10. Ran the JavaScript tests. For each class of test (sumloop, ack, array1, string), we started a new Netscape 4.03 process and visited the appropriate web page from js/index.html. We then copied the output with the mouse and pasted it into a file.
    Since one netscape process runs all the individual tests in a class of tests, memory allocation could be skewing the timing of the later individual tests.
