memory pool allocation (no replies)

Suppose, I am allocating a pool of greater than 4k(page size). Say for example I am calling the function ngx_create_pool with 8096.
But, this function will set the max as 4095 even if it has allocated 8K. Not sure, why is it being done like this.


p->max = (size < NGX_MAX_ALLOC_FROM_POOL) ? size : NGX_MAX_ALLOC_FROM_POOL;


I know, I have created a pool with size 8K, now I am allocating say 4K (4096) from this pool. I will call ngx_palloc with 4096. There we check if (size <= pool->max) which in this case will not satisfy and it will go and call ngx_palloc_large which inturn will allocate 4K.

This somehow is not sounding good. Why is ngx_create_pool putting a max value of page size even when it is allocating more. It is not doing chaining also.

Any expert opinions???
