  • Inconsistencies in wincache statistics page explained

    1 Comment

    Many customers running WinCache reported seeing different cache statistics on consecutive requests to wincache.php. Specifically, cache uptime and opcode cache summary returned second time by wincache.php was completely different than the data returned first time. Occasionally data shown in the opcode cache summary table didn’t match the chart displayed on its side. Many customers correctly guessed that this happens because there are multiple cache instances present in different php-cgi processes but thought that none of the PHP processes are sharing cache data and were worried about excessive memory usage by WinCache. I have been replying to many customers personally and posting on forums explaining why they see this behavior but as more and more customers are using WinCache, this question is becoming more common.

  • Feature additions and bug fixes coming up in WinCache

    No Comments

    We are seeing huge momentum behind adoption of WinCache. In the month of September, WinCache v1 Beta was downloaded more than 13,000 times making it one of the most downloaded IIS extensions in the first month following its release. Many happy customers chose to run it on their production servers despite its beta tag. We got very encouraging feedback from the beta release and we are pushing hard for our next release. Our next release date is approaching fast and I wanted to give an update on new features and bug fixes. If your favorite feature was missing in the beta and is also not in the list below, please email me or post on the forums so that we can consider it for future releases of WinCache. Read more ...

  • How WinCache make PHP run faster

    No Comments

    Why WinCache?
    Use of PHP accelerators is very common to make PHP run faster. Most of the existing PHP accelerators which are in use today are designed keeping *nix architecture in mind and mostly doesn’t work well on Windows. For example, APC which is very commonly used on *nix doesn’t work on Windows. Xcache does work in ISAPI mode but crashes when PHP is running in FastCGI mode with multiple php processes alive. Absence of a stable PHP accelerator on Windows made people complain about PHP performance on Windows all the time. Another complaint which we heard consistently from customers running PHP on windows was that file operations on Windows were slower than on *nix. Reason being Windows’s CreateFile system call which is much more expensive than a fopen call on *nix as CreateFile goes through a much more complex security check involving ACLs. Read more ...
