Just a heads up: tomorrow we will disable the System.Web directory
from compilation for a few hours as we land some fairly large changes to
it. We hope to complete the merging tomorrow, but if something goes
wrong we might spend some time over the weekend.
The new version of System.Web to be landed contains:
* Tests: 67,700 lines of new tests:
* NUnit test suite for about 50% of the controls.
* standalone tests.
running the tests for various web controls and validate
that they do the right thing.
Similar in spirit to NUnit, but for web pages.
* Unmanaged I/O: the new implementation uses unmanaged buffers
for uploads (HTTP POST for example) and content generation
as opposed to the managed buffers that we have today, which
greatly reduces the pressure on Mono's GC and also avoids
redundant copies of data by sharing buffers as much as
possible improving performance.
* Use of TCP Cork on Linux to avoid TCP glitches and delays,
this reduces the latency to get a full page.
* Support for Linux sendfile to transfer static pages (support
for more platforms will come later).
* XSP now transfers Socket ownership to the AppDomain to
avoid round trips and expensive AppDomain boundary crossing
* New controls: about 40% of the existing controls were
rewritten from scratch with test suites to validate their
* New application pipeline: a new iterators-based design
reduces the complexity and increases the maintainability
of the old version.
* Support for HttpClientCertificate on XSP, soon to come
* Improved tracing support.
Latency has been reduced in various key places and the new unmanaged
buffers accelerate the processing of medium and large sized pages (small
pages remain about the same speed) and large uploads wont disrupt your
