in thread thread-safe mmap module ?

You are hitting exactly the reason why I opened this node (smiles) - If I put Cache::FastMmap::WithWin32 in the apache startup.pl I'll hit this piece of code from the module:

sub CLONE {
  die "Cache::FastMmap::WithWin32 does not support threads sorry";
}

Damned I said ! Can't find a win32 thread-safe mmap alternative since then.

Let's see if I can come up with something you don't already know this time... The issue with support on Cache::FastMmap is likely that it uses unsupported-on-Windows C-code to handle file locking/unlocking. In the "Modules like this" section of the documentation, it references Cache::Mmap, which is a pure Perl solution, and thus should respect (to the extent possible) Win32 behaviors. A quick glance at the source suggests it should be fine with threading.	[reply]

Yep - googling on it I see that Cache:Mmap might work, and if not IPC::Mmap::Win32 name suggests it will -; I'll give it a try asap, crossing fingers about performance. Thanks to all of you !	[reply]
