[originally reported for ZFS on FreeBSD but Pawel Jakub Dawid says this problem also exists on Solaris hence this email.] Summary: on ZFS, overhead for reading a hole seems far worse than actual reading from a disk. Small buffers are used to make this overhead more visible. I ran the following script on both ZFS and UF2 filesystems. [Note that on FreeBSD cat uses a 4k buffer and md5 uses a 1k

If I have two vectors X<-1:10 Y<-1:5 When I combine them using cbind, the shorter one is repeated and both are made of the same length. Is there a methods that does this without duplicating the shorter one. I want to use this to store the data back to a file. Thanks ../Murli [[alternative HTML version deleted]]
