I guess that I should bite the bullet and switch to 5.5.
Yes.
I've been working on an evaluatorfork of APC optimized for CLI/GCI which tackles a lot of these issues head on and performs reasonable well, but I realise that this is a dead-end and will never get deployed, but I am currently considering regressing some of this technology into 5.5 and O+. Are you interested in a version of O+ which supports all SAPIs?
Yes, but there are some SAPIs that are more common, so these should be prioritized if trade-offs are required. My particular desire is for "embed" SAPI support. We use this in our Tuxedo application server, but it is a relatively niche use case.
In architectural terms I feel that having a universal cache option is important. It changes the mindset from something which is only used in niche performance use cases to a standard option. It also means that the cache can be stress tested by the entire php test suite. However, to do some of this you don't start with a patch, but with an RFC informed by evidence, and that's my real reason for doing this demonstrator.
I'm looking forward to seeing your suggestions and patches. Chris -- [email protected] http://twitter.com/ghrd Newly updated, free PHP & Oracle book: http://www.oracle.com/technetwork/topics/php/underground-php-oracle-manual-098250.html
