Don't discard buffer contents when recycling a B_MALLOC'ed buffer, but manage it using a secondary buffer cache that doesn't have as much overhead as the primary one (in particular, don't reserve BKVASIZE bytes of kernel virtual address space for each secondary buffer). This would be even more inelegant, and more complicated, but not so inefficient. Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
