Re: UPDATE slow

If this helps :)

db=# explain analyze update stats set clicks = 3344 where link_id=1;

QUERY PLAN

---------------------------------------------------------------------------------------
Index Scan using idx_link_id on stats
(cost=0.00..149.42 rows=50 width=30) (actual time=0.58..727.45 rows=9994 loops=1)
  Index Cond: (link_id = 1)
Total runtime: 8361.93 msec
(3 rows)

Just tried it on Linux - still takes 5-10 seconds. Any speed-up tips? Also tried it on MySQL and the update is nearly instantaneous :(.

I have about 11000 rows and this query is much slower than I expected:

update stats set clicks = 123;

stats is basically just: id, clicks; with indexes on each. Right now, the query takes about 10 seconds to execute. It's also on windows 2000/cygwin (if that contributes to slowness). Is it normal for updates like this on that many rows to take a while?
