If the loadlib has a very small blocksiZe (e.g. 1000 bytes, which we found in an IMS load library) that causes a frequently loaded module to be in MANY extents, there can be response time impact of seconds per transaction when those multi-extent members are loaded. Using half-track blocksize will mitigate against that kind of stupidity we found in our IMS folks who had chosen that small blocksize "to make more use of disk space" (which was itself an incorrect choice).
It is often better to use 32,760 for load libraries than to use any smaller block size, and it's never worse.
