Hi, I've been working on a patch provided by wollman@, where he uses UMA instead of malloc() to allocate an iovec array for use by the NFS server's read. So, my question is: When is it preferable to use UMA(9) vs malloc(9) if the allocation is going to be a fixed size? Thanks in advance for any info, rick
