In Sun's release notes for Netscape 7, they suggest adding the following
shared memory settings to /etc/system to improve gtk performance:
set shmsys:shminfo_shmmax = 0x2000000
set shmsys:shminfo_shmmni = 0x1000
set shmsys:shminfo_shmseg = 0x100
(see http://docs.sun.com/source/817-0807/index.html).
Note that we are already setting shmmax and shmseg in /etc/system
as follows:
set shmsys:shminfo_shmmax=16777216
set shmsys:shminfo_shmseg=8
These settings were apparently added long ago for MAE, which I imagine
we no longer care about. (The Sun shmmax value doubles our current
setting; the default value for shmmni (shared memory identifiers) is
100 (decimal)).
I tried running with the settings recommended by Sun, and there might
have been a slight improvement; certainly there were no bad effects.
It would be nice if someone who uses a Sun more intensively could try
out these settings, but if no one knows of a reason why they would be
harmful, perhaps we should just make this change in the release.
