I'm asking them for (real) benchmarks, thanks for the advice. (fio is not available for us now to do it myself, grmbl)
It just occurred to me that it is not necessarily the case that reading the indexes causes a lot of random I/O (on the index itself).
I mean, maybe the index is generally read sequentially and then, when retrieving the data, there is a lot of random I/O.
if it's a long story, any tips for info about this (book or web site)?
cheers,
wbl
