Hi,

Has anyone detect performace decrease when going from Gauntlet 3.1.1 to 3.2 ?

We have a SPARC20 module 71 (SUN OS 4.1.4) with 256 Mbyte RAM and useing
three ethernet interface's.

Interface 1, Internet
Interface 2, Internal net.
Interface 3, DMZ (for our www)

Statistics of twenty-four hours.

Total messages: 1125  (8851 Kb)
FTP service users (total: 3599)

DNet service input thruput (total Kbytes: 1022337)=> Number of users/sites 4752

The performance on Gauntlet 3.2 was so bad that we had to go back to 3.1.1.
Maybe the SUN OS was not right installed ? (We did not install alla patch's
for SUN OS 4.1.4., wich our Gauntlet reseller recommended)
Maybe we should install a patch that increase the number of socket's ?
Maybe we should do this and that ?

But, what should we do to get the most of our SUNSPARC20 with Gauntlet ?

Thanks in advance !

/Lars
