Thanks for the numbers, Bart.
If that were the only limiting case... sounds like a design flaw to me
then.
Oracle is still officially supporting all(?) sun4v machines.
If IPS is really performaning *that* badly... sounds like it needs some
design tweaks to make it perform better on the full range of oracle
supported hardware.
That being said... The issues I'm seeing, cant only be due to that.
OpsCenter 3.1.1 driven installs, go ludicrously slowly, and usually time
out after 3 hours.
But, if I do a manually triggered, "installadm" based install, I can get
solaris 11 installed to an older sparc (a T2000, even), under 1 hour.
Actually, closer to half an hour
So seems like there's multiple issues at play here. One could be the
slower JSON parsing performance, perhaps. The other may be poor SSL
management on top of that.
Comparison of differences ---
* Direct installadm+net boot: no SSL, goes directly to port 80 standard
solaris 11 pkg services
Console output says that the combined stages of "figure out which
packages I need"
and "actually download the packages", takes around 15 minutes only.
Download itself only takes 10 minutes
20:17:00 Download: Completed 585.26 MB in 555.40 seconds (1.1M/s)
Then running the requisite 88,000 actions, takes another 15 minutes or so.
20:30:58 Actions: Completed 88134 actions in 776.30 seconds.
* OpsCenter: Over SSL, and goes to funky redirection port+URL
https://server:8002/IPS/
Additionally, opscenter seems to want to include every solaris11 package
ever released, in its pkg repo.
So whereas "pkgrepo list |wc -l" only returns around 4400 on the direct
case above,
it returns over 9000 for the opscenter case.
If "more packages in repo" degrades install time, even when the client
doesnt even need the extra packages... there's a problem in efficiency
of IPS mechanisms somewhere.
