InstantDB: Tremendously long time for an update


Hello, all --

First off, I have fastUpdate set to 1, searchDeletes set to 0, and even turned 
journaling off with transLevel set to 0, just in case.

I need to do an update setting the value of a tinyint column for every row in a 
92,000 row table.  When I try this, InstantDB churns along for an hour or more 
working on the update, which is *way* too long to be useful.  I've actually 
never let it finish, since an hour is far beyond acceptable for this 
application.  

For example, if I have a table like the following:

CREATE TABLE test(prod_id varchar(16) PRIMARY KEY, status tinyint)

I want to set status to 0.  The natural thing is to do

UPDATE test SET status = 0

However, it's actually much quicker, believe it or not, to do this:

1) SELECT prod_id INTO tmp FROM test
2) DROP TABLE test
3) SELECT prod_id, 0 INTO test FROM tmp
4) DROP TABLE tmp

The above workaround takes about 15 minutes to complete for around 92000 rows, 
which is barely acceptable for the application: but much faster than simply 
updating the original table!  My question is, does anyone have any more tips on 
speeding up updates?  All I can find in the docs and mailing list archives is 
mention of the fastUpdate and searchDeletes parameters.

btw, The only index on the table is the primary key.

Regards, and thanks for any help!
Liam
