Starting Squeak on Windows


*	The naive way
Double click on the Squeak VM (Squeak.exe). Note that this method has some
disadvantages. Since the VM does not know what image file to use it must
search the disk. I have seen this method to take various seconds to
complete. In addition, if there is none or more than one image file you will
be prompted with a file dialog to select the one you want to use.

Hi Andreas & John, 

For what it's worth, I have two Windows NT 4 machines and a Windows ME
machine, and here are some very approximate (i.e. measure with a clock on
the wall) startup times for Squeak3.2-4956 using Squeak 3.2.3/Tea 1.8 VM
(release from Sep 5 2002, compiler gcc 2.95.2 19991024 (release). 
My idea of startup time is time from double-click on Squeak.exe until the
Squeak window appears. 

CPU                                OS                        Physical
Startup Time        Bytecodes        Sends 
                                                        RAM 
1.4 GHz Pentium 4                WinNT4SP5                512M
~16 seconds                ~119M/Sec        ~2.90M/Sec 
450 MHz Pentium II        WinNT4SP6                256M                ~18
seconds                ~ 44M/Sec        ~1.26M/Sec 
700 MHz Pentium III        WinMe                        128M
~ 2 seconds                ~ 67M/Sec        ~1.94M/Sec 

These are very coarse measurements, but the two NT machines take about the
same time to start up and the ME machine is much, much faster, while
tinyBenchmarks more closely reflects the clock speeds of the CPU. 

Any ideas to explain this? 


                                                                -Dean

Another thought: Is it possible that you're allocating the memory lazily and
the image loading process hits the exception handler upon first access to
each memory page? This might slow down things quite a bit. In the Windows VM
I am actually pre-allocating the memory needed for the image data (plus some
extra) before the read comes along to avoid this.

Cheers,
