An intro to vice posting policy..
by Børge Kjeldstad 05 Sep '03

Hi, I have just been noticed I posted my messages in html. I am realy sorry for this. I did not know I did, and did not even know what posting in html was. However, now I have pressed som buttons in the email program and I hope it is now ok. Please tell me if not :) Now, having become aware that I was misdoing, I looked for some guidelines on vice posting policy. The intuitiv places to look were: 1. The welcome message I received when I subscribed to the zope list 2. The webpage were I administrate my member options 3. The zope.org/Resources/MailingLists page Unfortunately I found no such guidelines on these pages. My question is then: Would it be beneficial to have some such guidelines on one or more of these places? To many members such guidelines are surely not needed, but for some they may be of help. I see at least two possible ways to include such guidelines on one or more of the three places mentioned above: 1. Simply just include a link to some site on the internet were vice posting policy is described. 2. Make a checklist and have a link to it. The checklist could be like this: - Edit your subject line to avoid ..... - Do not post your messages in html. To confirm that you do not, do the following: ..... - Edit message body when replying. For instance you should cut away... - - - etc. Best! Børge

Hyperthreading is only virtual processor not physical. In Linux with smp kernel that know HT features you get only 5-30% increase in computing power depends on kind of computing. So you could be quiet with Zope, if Zope will be boound in CPU0 then system consume power from CPU1. > Say you have a dual-processor HT machine, running two Zope.

Will this configuration perform > better? I think that you will get most performacne with two Zope instances. HT technology is only moneymakers marketing tool for thumbs. If you want best available performacne for low price (ie., does not use processors targetted for servers), use dual P-III Celeron CPU instead of dual P-4 with HT, you will get much more performance with this oldies but goldies...

I must have apply my patch for internationalizing zope for my charset (windows-1250). Search Zope howtos for name "lukesh". Here is a TGZ, where are all changed zope system files. Now zope works fine, but before them it is sometimes mixed codepages if you use different browsers to fill data (ie. MSIE4 and MSIE6). But it is for Zope 2.5.1, newer Zope has some property to set charset but I dont know their name and parameters. Try to search mailinglist. Regards, JL.

Zope Processor binding and Hyper Threading
by zhimin＠iss.nus.edu.sg 05 Sep '03

05 Sep '03

Hi, On a multi-processor machine running multiple Zope instances, it's known that each Zope/Python process should be bound to a single processor to increase performance. If you have a dual processor machine running two Zope, setting the affinity is easy - one processor per zope. Now we have processor with Hyper Threading (HT) technology, how do you set the processor affinity for maximum performance? Say you have a dual-processor HT machine, running two Zope. You'll get 4 virtual cpus: 0, 1, 2, 3. 0 and 2 are on one physical processor; 1 and 3 are on the other physical processor. You can bind: 1) Zope1 to cpu0 and cpu2 ; Zope2 to cpu1 and cpu3 2) Zope1 to cpu0 and cpu1 ; Zope2 to cpu2 and cpu3 3) Zope1 to cpu0 ; Zope2 to cpu1 4) Zope1 to cpu0 ; Zope2 to cpu2 Which one will give the most performance? Will the switching of Python's global interpreter lock between two virtual cpus on the same physical cpu slow down the system? Another way is to run 4 Zope instances on the dual-processor HT machine, and bind one Zope to each virtual cpu. Will this configuration perform better? Thanks! Regards,
