Is it possible to determine/get the block size that can be used by a system? I have the information below that provides some insight, but is it possible to obtain this information from configure?
Size of DB input buffer blocks. Normally, this is set by indicating which machine you are on. The default size is 4096. For large mainframes it is set to 10240. For vaxen it is set to 6144. (See hdr/udbio.h.) This definition can affect the number of reads done to get data and the amount of internal fragmentation there is in memory (since a block cannot be re-used until all attributes in the block are unused). The blocksize is determined by the data stored in the file iosize, that can be found in the package document directory. The file iosize contains the following: 3b2 4096 3b20 4096 alliant 4096 i386 4096 mips 4096 pyr 4096 sun3 4096 vax 6144 hppa 8192 i486 8192 ilinux 8192 sparc 8192 ibm 10240 uts4 10240 solaris 16384 -- Richard Bos Without a home the journey is endless
