Hi Tom,

I did that when I have stopped my updates.

Now, I am doing updates below is the output of vacuum.
After doing the vacuum verbose analyze, it reported the following :

INFO: vacuuming "craft.dsperf_rda_or_key"
INFO: index "hello242_1105" now contains 1792276 row versions in 6237 pages

So what's the problem? That doesn't seem like a particularly bloated index. You didn't say what datatype the index is on, but making the most optimistic assumptions, index entries must use at least 16 bytes each. You're getting about 300 entries per page, compared to the theoretical limit of 512 ... actually more, since I'm not allowing for upper btree levels in this calculation ... which says to me that the page loading is right around the expected btree loading of 2/3.
