CPSSkins perfs

Hi! I usually don't read the posts on zope-list, but I found this one: http://mail.zope.org/pipermail/zope/2005-September/161330.html sorry this is a bit old, but ... M. Davis, what are your benchmark figures based on? I just ran a quick benchmark on Plone's front page and found: siege -v -r 10 -c 1 http://localhost:8080/plone ** siege 2.61 ** Preparing 1 concurrent users for battle. The server is now under siege... ... done. Transactions: 10 hits Availability: 100.00 % Elapsed time: 2.43 secs Data transferred: 258630 bytes Response time: 0.24 secs Transaction rate: 4.12 trans/sec Throughput: 106432.10 bytes/sec Concurrency: 1.00 Successful transactions: 10 Failed transactions: 0 Longest transaction: 0.29 <---------------- Shortest transaction: 0.23 <---------------- then installed CPSSkins, replaced the calendar portlet with a calendar templet and placed it in the cache and I got: siege -v -r 10 -c 1 http://localhost:8080/plone ** siege 2.61 ** Preparing 1 concurrent users for battle. The server is now under siege... ... done. Transactions: 10 hits Availability: 100.00 % Elapsed time: 2.00 secs Data transferred: 247360 bytes Response time: 0.20 secs Transaction rate: 5.00 trans/sec Throughput: 123680.00 bytes/sec Concurrency: 1.00 Successful transactions: 10 Failed transactions: 0 Longest transaction: 0.23 <------------- Shortest transaction: 0.19 <-------------- which makes Plone with CPSSkins faster than Plone without CPSSkins by caching just one portlet. And this is still far above the figures you can get by caching all portlets (cf. CPSPortlets), in that case a request will not take more than 0.1 seconds to complete. Also, putting most of the page content in the RAM cache has made it possible on sites with a lot of access to minimize the zope-2.7 read conflict errors which has now be solved in zope-2.8. regards /JM

Passing args to PageTemplateFile instances
by Anders Bruun Olsen 23 Sep '05

23 Sep '05

Hi, I have read some posts about this before, but the solutions given there does not seem to work for me. The deal is that I would like to make a product where amongst other things there needs to be a search feature. I then make a method that takes input from a form with searchwords but then I get stuck. How do I get the search results handed over to a ZPT that will display them? I would like to just pass the results as an argument to it, and have made a simple test-product to test how this would work. class TestProd(SimpleItem): """A TestProd object""" meta_type = "TestProd" manage_options = ( {"label": "Edit", "action": "manage_main"}, {"label": "View", "action": "index_html"}) manage_main = PageTemplateFile("templates/mainTestProd", globals()) index_html = PageTemplateFile("templates/indexTestProd", globals()) test = PageTemplateFile("templates/test", globals()) def __init__(self, id, title): self.id = id self.title = title def testit(self, REQUEST=None): return self.test.__of__(self)(something="blah") In the template I should now be able to access options/something according to previous posts, but this: <span tal:replace="options/something"/> results in: Error Type: KeyError Error Value: 'something' I am using Zope 2.8.0. Am I doing it wrong? How can it be done correctly? -- Anders -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS/O d--@ s:+ a-- C++ UL+++$ P++ L+++ E- W+ N(+) o K? w O-- M- V PS+ PE@ Y+ PGP+ t 5 X R+ tv+ b++ DI+++ D+ G e- h !r y? ------END GEEK CODE BLOCK------ PGPKey: http://random.sks.keyserver.penguin.de:11371/pks/lookup?op=get&search=0xD4D…

Zope scalability / efficiency question
by mark hellewell 22 Sep '05

22 Sep '05

Hi everyone, I've got a question I'd really appreciate some input on. If I'm running perhaps a dozen Zope sites, experiencing anywhere between several hits per second to a lot less, would it potentially be more efficient (decreased latency etc.) to run each site as its own Zope instance or have one Zope instance running muliple (CMF based) sites. I haven't even thought about adding ZEO into the mix yet. The basic aim of the exercise is to find out how many usable zope instances / sites I could get onto a typical mid-range modern server. I know it's a bit of a "how long are your pieces of string" sort of question, but any help you could offer would be gratefully accepted! If anyway has any experience of this sort of setup and can offer a little insight it might reduce the amount of testing I have to do myself. Many thanks, Mark

Membership website
by Javier Godinez 22 Sep '05

22 Sep '05

Anyone, Hi, noo-bee here, I need some direction, not sure if I should build my site from the ground up, or if there are templates that I can use out there. I am trying to decide how to go about building site where users can signup for an account by confirming their email address. They will also have profiles and a rating system. If anyone can direct me where to start, I will really appreciate it, the tutorials where really basic and didnt get into the details of sending emails or how to keep a user database with encrypted passwords to authenticate users. Thank you so much, Javier Godinez

No access to ZMI but plone instances work
by Michael Zimmermann 21 Sep '05

21 Sep '05

Hi there, after an upgrade from debian woody to debian sarge I do have the problem that I can not access the ZMI any more. I. e. if I do some.domain.com:8080/manage my browser is unable to show the page and complains about: text/x-unknown-content-type. But if I access a plone instance located in some.domain.com:8080/ploneInstance all works as expected. It seems that the zmi page in zope does not "deliver" the right content type for the browser to handle while the plone instances do... This I tested with different browsers on different machines. So I think it is a zope issue. But what to do now? Zope and python is compiled from source and was just not changed during the woody to sarge upgrade. Using: python 2.3.5 zope 2.7.6 -- cu, Michael --------------------------- | mz-list(a)incunabulum.de | --------------------------

Getting at third-party modules in dtml?
by Paul Winkler 21 Sep '05

21 Sep '05

I've got an ancient DTMLFile UI that I need to add a feature to, and I really don't want to have to rewrite it all in ZPT today... I'd love to, just don't have time now... and there's something I just can't figure out: Say I have a function that I want to make callable in my UI. It needs to be globally available, i.e. it needs to be callable *without* having an instance of my product yet. (This has to do with listing information about all acquirable instances of the product, so the user can choose from those available.) I can make the security declarations fine, e.g. ModuleSecurityInfo('Products.MyProduct.utils').declarePublic('getBaz') .... and then I can import and use getBaz() in python Scripts, and I can use it in ZPT too by doing something like python:modules['Products.MyProduct.utils'].doBaz() .... but how the heck do I do that in DTML? There's no "modules" namespace in DTML anywhere that I can find... I guess I could wrap the function in an external method. But since this UI is for a product I maintain, I REALLY do not want to have to add goofy stuff like that to the installation instructions and make my users clutter their ZODB with external methods. That's way too fragile and messy. Thanks, PW

Multiple databases/instances
by Eric Wohnlich 21 Sep '05

21 Sep '05

I'm working on the scalability aspect of Zope, and am trying to see what the best practices are for creating multiple databases or multiple Zope instances. I am using ZEO and have allowed for multiple databases (Data.fsfiles) by editing zeo.conf just to try that out, because our current database is getting very large. The way I understand it, ZEO allows the work load to be distributed among multiple clients when you are getting a lot of hits, but does not address the issue of having a very large database for which it may slow down. So for this you would either create multiple instances of Zope/ZEO which each have their own database, or you would just create multiple databases within a single Zope/ZEO instance. Is there what is considered a best practice as far as choosing one of these options? Is there a database size I should try to maintain by distributing my Plone sites among different databases - or maybe just have a separate database for each? Or perhaps I am way off... Eric

Title or ID question
by Phil Beardmore 21 Sep '05

21 Sep '05

Hi All, this may be a simple question, and I'm still trying to get to grips with Plone so I hope you can help. I want to add the page title into a Plone Document, and also a Zope Page Template. I know in DTML is just a case of inserting the following line: <dtml-var title_or_id> But I'm unsure of how to do it in ZPT and Plone Document. Hope you understand my question and can help. All the best Phil
