Reducing Requests-Setup-Costs

Back in the times of the first implementations of mod-cml I took the request setup costs as the root of all evil. They were the problem I wanted to fix with mod-cml.

But what is the request setup cost ? What is influencing the request-time ? Where can you influence it ?

PRE-RELEASE: lighttpd-1.4.13-r1385

It looks like mod_magnet gets more and more attraction.

Against the least pre-release we have some minor bug-fixes and the new lighty.stat() function for mod-magnet which is using our internal stat-cache to reduce the number of stat() calls which hit the kernel. darix had some nice benchmarks on it.

Trunk Is Trunk

darix just moved the svn-trees around. Now trunk/ is containing the code for 1.5.0 (formerly known as branches/lighttpd-merge-1.4.x) and branches/lighttpd-1.4.x is taking care of the 1.4.x series (formerly branches/lighttpd-1.4.11-ssl-fixes). "[1352]"://trac.lighttpd.net/trac/changeset/1352 got commited to the 1.4.x-branch to fix a crash in 1.4.12.

RELEASE: Lighttpd 1.4.12

I’m very proud to announce the release of 1.4.12.

After 8 pre-releases and several cross-compiles and test-runs no new bugs were found and you should have a solid and stable release in your hands.

Over the 1.4.11 was available for download (03/2006 – now) the number of lighty installations raised from 27 103 to 120 442 according to netcraft.com. That’s amazing. It was important for us to create a release is good enough to replace 1.4.11.

This release fixes several long-standing bugs like

  • SSL hangs with Opera (we added work-around for a bug in Opera)
  • a long list of fixes for SSL in general
  • added ssl.use-sslv2 and ssl.cipher-list for all who have to
    comply with PCI

and only added a 2 really new features:

  • (experimental) LOCK support for webdav
  • mod_magnet as long-term replacement for mod_cml

On mod_cml:

  • mod_cml is deprecated from now on
  • it will be removed in 1.5.0
  • mod_magnet provides the same functionality and more with a
    cleaner syntax and in a more generic form

Optimizing PHP + FastCGI

Over the last evenings I helped several lighty users to tune their application stack. Instead of telling the same story over and over again I wrote it down into a wiki page: "wiki://Docs:PerformanceFastCGI"://trac.lighttpd.net/trac/wiki/Docs%3APerformanceFastCGI Over time this will be the main source for application tuning, hints and secrets.

XCache's Demo

It has been about 5 months since the first announcement of XCache.
But many of you may still wonder how XCache “looks” like. So i’ve spent some hours and finally setup Administration demo page and
Coverage viewer demo page

XCache was stable (the cacher stufs), but now becomes more stable (installing, configuring), and seems a bit hot recently if you may google for “php” +"xcache" :)

Thanks for your support and encourage, XCache will goes on and on..
