New subject: [xwiki-users] Slow public web site

8 Jan 2007

Hi,

I am glad to hear that xwiki.org had a spike in visits.

Regarding the access to JIRA, I still have a problem and it looks like a DNS
configuration issue.

Investigations using a DNS diagnostics site give the following results:

How I am searching:
Searching for jira.xwiki.org A record at i.root-servers.net [192.36.148.17]:
Got referral to TLD3.ULTRADNS.org. (zone: org.) [took 187 ms]
Searching for jira.xwiki.org A record at TLD3.ULTRADNS.org. [199.7.66.1]:
Got referral to lanai.xpertnet.biz. (zone: xwiki.org.) [took 3 ms]
Searching for jira.xwiki.org A record at lanai.xpertnet.biz.
[195.242.99.118]: Reports that laam.xpertnet.biz. does not exist.  [took 196
ms]

Response:
jira.xwiki.org. exists, and is a CNAME pointing to laam.xpertnet.biz., which
does not exist

Details:
This is a very unusual response, and indicates that the DNS server is
authoritative for both jira.xwiki.org. and laam.xpertnet.biz. and that while
jira.xwiki.org. exists, it knows that laam.xpertnet.biz. does not exist.
See RFC2308 2.1 for details.

Thanks,

	Olivier

Hi,

We have had both some spam attacks which are slowing down the frontal 
servers and a spike in visits thanks the the Groovy 1.0 Release news 
which has mentionned XWiki.
We are trying to tweak things around to improve the performance and will 
consider moving to more powerfull servers..

Is JIRA still down for you ? It's working fine for me.

  Hi Oliver,

 From personal experience, there can be some longish delays to the 
 first page access after a server restart as macros etc are compiled.

 Having said that just trying to download 
 http://www.xwiki.org/xwiki/skins/xwiki10b1/logo.png take a good 1/2 
 second - perhaps xwiki.org <http://xwiki.org> isn't deployed to a 
 hugely powerful server / big a pipe as the other wiki's you've seen.

 With the server I have installed, the performance is acceptable & it's 
 only running on a 1.4 PIII with 1GB ram desktop machine !

 Cheers,
 Dan

     Hi,

     I have been doing some research on wikis and looking at
     www.xwiki.org <http://www.xwiki.org/> throughout the week and
     observed slow response times pretty much consistently, compared to
     other sites on the internet.

     http://www.xwiki.org/xwiki/bin/view/Main/WebHome
     <http://www.xwiki.org/xwiki/bin/view/Main/WebHome> has taken up to
     15 seconds to display.

     What can explain this?

     Thanks,

                 Olivier
