We are using a class library called Objectspace from Recursionsw. We did a small test program. This program has an object with about 20 fields (total of around 200 bytes). All we do is write this object (binary stream over socket) from one process and read it from the other process. For banchmarking we write and read this object 200 times.
The results are as follows:
Solaris 2.5.1 - Around 13 seconds
Solaris 7 - Around 60 seconds
Solaris 8 - Around 120 secinds
Solaris 9 - 1-2 seconds

This is without any change in the source code. On Solaris i have tried using boths std streams and classic iostreams. Can anyone give any clues as to what is going wrong.
Regards,
Manoj

Hello


Could it be something in the way the windowing size is done between the different flavours of solaris? IF your using the same class library then the only variable is solaris,
