multiple segments of shared memory?

Is there any way to use segmented pools of shared memory in APC? In other words, as far as I can tell, all apc_add() calls store their values in a single pool of memory whose size is set in php.ini. However, I'd love to be able to set a limit on how much data a particular apc_add() call can store, separate from the global limit. Something like this: $m=apc_create_segment('32MB'); // create a segment of memory from the global memory space, with a cap of 32MB apc_add('foo','bar',300,$m); echo apc_fetch('foo'); This would seem to open up a whole new area of optimizations, because then you can put a cap on a specific variable in your application, that would allow shared memory to be utilized up to a point while allowing the remainder of the global shared memory to remain free for more critical data to be stored. I know apc_inc() and apc_dec() could help me place a cap on the number of times a particular type of variable could be stored, but this is not satisfactory because 1) the data being stored might be of variable length, and I'd want a cap on the memory being used rather than the number of values being stored and 2) there's the overhead of constantly calling apc_inc()/apc_dec() just to keep track of cache usage. ------------------------------------------------------------------ Alexander Romanovich • alex@whitewhale.net Technical Director White Whale Web Services, Inc.
