64K strips? is that like 64k bytes, (i.e. 64 * 1024 = 65536 bytes?)

Hi all,

There have 180 user license, some of them are using vb application (about 15
uvcs), 20 uv-net connection, about 60 telnet connection and 20 of fixed tty
dump terminal users.

Some of the user are using SAME user id to login to universe is that will
cost the issue ?

I have double up the swap spaces from 4gb to 8gb. but i still having the
performance degraded issue. below is the usages of swap spaces before and
after increment. The user claim that the system starting slow after 48
hours, so the mis guys have to restart universe every 48 hours.

[ServerX1]:/>lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto
Type
hd6             hdisk0            rootvg        4096MB     1     yes   yes
lv


[ServerX1]:/>lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto
Type
paging00        hdisk0            rootvg        4096MB     1     yes   yes
lv
hd6             hdisk0            rootvg        4096MB     1     yes   yes
lv


The above output showing that the system only using 1% of the swap spaces
even i have increase the size to 8gb. Is that any uvconfig parameter that i
need to configure to "tell universe" that i have 8gb of swap spaces.


tty:      tin         tout   avg-cpu:  % user    % sys     % idle    %

hdisk4          28.9     112.4      34.8          0       113
cd0              0.0       0.0       0.0          0         0


Above is the output of iostat. hdisk2 & hdisk4 are configured as RAID5 with
64k of strips and mirrored each other.

Please advise,
thank you
