-S while running as a service under Windows (and probably as a daemon under Unix although I'm in Win32 land) seems to add a 'Restart' button to your Zope control panel. Thus you can restart Zope from the management interface which is kinda handy, assuming Zope is still happy to present the management interface to you. And you are quite correct this option doesn't appear to be documented anywhere.

This discussion is so pointless...
Pointless to whom? I'm learning a good bit.
FYI Google has upwards of 10.000 (thats TEN THOUSAND) linux machines serving as frontends for their service. And although Google's pages are dynamic, they're basically the same script run over and over again with little or no images. So caching is not the only option; its just that I'm sure you dont have Google's
budget.
What you're trying to do is asking Zope to DYNAMICALLY generate Squishdot pages (probably full of database accesses and images). But you're doing this on a PC (no hardware specs were specified) running Windows (!) and on a DSL line.
Hardware specs were most certainly provided (P3 850MHz 768MB RAM). I hate to be put in the position of defending Microsoft, but the OS didn't fall over. Neither did my DSL connection. Zope did. As of about 8:00 PM CST today my site has served more than 120,000 pageviews. Not bad, and it's settled down now, but I was having to restart Zope every hour or so for most of the day.
If you try to do something similar with ANY OTHER platform (lets say Apache+PHP+PHPNuke; or IIS+ASP+some forum software or other) you're also going to get into the same kind of problems.
Agreed. But I'm not sure the other options would fall over.
If you compound this with the fact that you're also clueless (e.g
running
Zope without knowing what -S is for; or, for that matter, running any
software without knowing what you're doing), you're in for a lot of trouble. Please, dont answer "I'm a writer, not a programmer". THAT is precisely your problem. You want to be able to build rockets without taking a course in rocket science. Dont misunderstand me; you can still fire rockets or build amateur rockets; just dont try to reach the moon.
First of all, I never claimed to be cluefull. That's why I came here and asked the question. But neither am I clueless. The -S switch has been bothering me for a while. Do a search on zope.org for "command line switches" nothing. Nothing in any of the Zope documentation that I can find. Nor in any of the three Zope books currently in print. Even the Windows-specific doc doesn't say anything about the -S switch. Being a writer/information architect isn't my problem. Nor is it relevant to this issue. Get used to it; we're here and we need your help. But you need our help just as much. And to use your metaphor, I have no interest in building rockets, only flying them. Better get used to that too; there are a lot more of us than there are of you.
Here are some tips:
- enable caching on Zope
Done and already cited.
- change from Windows to Linux
Maybe, but again, Windows didn't fall over--Zope did.
- install more RAM on your PC
768Mb is the maximum I can install in what I've got. Should be adequate. There's no evidence of not having enough memory caused Zope to fail.
- get more CPU for your PC
Again, there's no evidence that lack of CPU horsepower caused Zope to fail.
- put Squid in front of your Zope
Excellent advice for Linux users.
- fine tune your Zope to use only the necessary command line switches
So what's -S for? As stated in a previous message the only other switches I'm using set the web port and the WebDAV port.
- pack your Zope database frequently
I do. At least weekly, sometimes daily, today it was every few hours.
- stop all the other software that you might have running (i.e. dedicated server)
Zope's all that's really running.
- create static versions of the most accessed page(s)
That's a good idea.
- you might have a memory leak somewhere; plug it
We're running a consumer portal with about 1 million hits per day using 2 frontends (regular PC machines) connected to 1 backend (server PC).
C U!
