WHY is it so slow???? How can we speed it up? help fix this wonderful

on a t2000 and it takes anywhere form 6-10 seconds to pull up a page after clicking on the link.

I LOVE everything about the TWiki except the speed.

if you could work on anything for next release work on the speed please!

Re: WHY is it so slow???? How can we speed it up? help fix this wonderful

3 main options:

1) Use a dedicated server so that the perl scripts run faster

2) Set your server to pre-compile the perl scripts : mod_perl

3) Use the Twiki CacheAddOn  to cache automatically HTML version of your topics

More info: http://twiki.org/cgi-bin/view/TWiki/Per … Supplement

By the way, twiki.org is VERY slow. They have not applied the above recommendations. Why??? Too costly for such a big site?

Let us know how it goes.

Page load time on my intranet TWiki (entry level dedicated hosted server with Linux, Celeron 2.0 MHz, 512 MB RAM) is around 1.5 sec. This is with plain cgi. Speed is doubled if you run TWiki under mod_perl or PersistentPerl.

Something must be odd with your setup. Please post a support question in the TWiki Support web.

TWiki.org is on an aging SPARC, CPU is constantly at 100% utilization. We have exactly $0 budget and need a new sponsor for new server hardware. (We have a generous sponsor for server co-location.)

Peter,

Concerning Twiki.org, it might be a good idea to raise some money via donation. This is the standard way to keep great open/free source project up and running. I am afraid that the slowness of twiki.org will give a bad image of Twiki. You could add on the home page of Twiki.org a message explaining why it is so slow and inviting people to contribute financially to a more powerful hosting. Wikimedia raised almost 1.000.000$ in a few months. Why not Twiki!!!  In addition you should also invite all the happy customers to donate or to host Twiki.org: yahoo, WaltDsney, ...

Meanwhile, would it be feasible to cache some of the Twiki.org webs?

Anyway, great work altogether.

Thanks kurgbe for your concern, this is kind of you. Yes, caching is an option.

I have some sponsor in the pipleline for a new server, stay tuned.

We are considering a fund raising program. This needs the right infrastructure, a registered non-profit org and proper administration. For tax implications and community reasons I can't accept monitary donations as an individual on behalf of the TWiki project. (However, I spent over 10,000 volunteer hours on the open source TWiki project over the last 8 years, and spend more than a thousand dollars a year on travel for my speaker engagements. Therefore I appreciate donations for my personal work I am doing for TWiki.)

Re: WHY is it so slow???? How can we speed it up? help fix this wonderful

We recently deploy Twiki 4.2 on the T2000 box with 32 GB RAM (with coolstack installed and configured).
We also use mod_perl, but the page view especially using search results slower than the same page deployed in v240 with 8 GB RAM.

Any insight?  Below is an example the search page we used:

%TABLE{ tableborder="1" cellpadding="1" sort="on"  initsort="1"}%
| *Project ID* | *Status* |
%SEARCH{search="META:FORM{name=\".*IsveWWPCobraForm\";META:FIELD{.*?Stage.*?value=\"Execution.*\"}" regex="on" scope="text" nosearch="on"  order="modified" web="MDE"  format="| $formfield(Project ID) |$formfield(Status) | " }%


Thanks for your help!

T2000 is simply not the right hardware for CGI traffic. If Sun hardware I recommend an Intel Xeon based system such as the X4450.

Please ask support questions in the Support web on twiki.org, http://twiki.org/cgi-bin/view/Support/WebHome (many people are watching that forum)
