Question

I have a similar problem to the SaveForever question that was asked about the Beta release. We are using LDAP authorization through the .htaccess file in the bin directory.

I have done some experiments and found that if I use the directive to only require a user name for POST and PUT, I get a 2-5 minute hang on the first upload in a browser session. All subsequent uploads are fast. If I add the GET limit and require the user to log in to read the twiki, the problem does not occur.

Users have complained about needing to login (don't get me started...) to read the twiki. So I'm trying to find an alternate solution.

I've also noted that there are two POST requests in the apache access_log that are 2 minutes apart. The first POST does not have my user name and the second one does. At that point each upload has a user name:

192.168.1.13 - - [13/Jul/2007:14:00:07 -0400] "POST /twiki/bin/upload/Sandbox/TestTopic0 HTTP/1.1" 401 30847 "http://al/twiki/bin/attach/Sandbox/TestTopic0" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0"
192.168.1.13 - rsayde [13/Jul/2007:14:02:07 -0400] "POST /twiki/bin/upload/Sandbox/TestTopic0 HTTP/1.1" 302 33 "http://al/twiki/bin/attach/Sandbox/TestTopic0" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0"

I'd like to reopen this question. I'm also facing the exact problems mentioned here. Another thing that I've observed is that if the size of the first upload/post is a small, the performance is ok. But if the size is bigger, the slow performance is experienced. I've tested with postings of 1500 bytes and 6500 bytes.

I'm at a loss of how to further troubleshoot this issue. Would appreciate any help.

I have the same problem, as was also reported in SaveAndAttachScriptsVerySlow. This problem is reported in different environments (linux, windows, apache, indigoperl) so it seems to be in TWiki not in external factors. It seems it is a real problem, whose causes are worth enough to deserve some investigation from those who can understand TWiki insides.

Yes, still needed. The solution has not come out yet.

If I change the Login Manager to use TWiki::Client::TemplateLogin, instead of TWiki::Client::ApacheLogin, this problem did not occur. Remember to also comment out the appropriate LDAP authentication directives from the Apache configuration file.
