Yes Javascript is not the fastest of languages. The code started out on
another project which had just a couple
of hundred entries. Its speed was quite acceptable and it had the
advantage of running offline by just saving the
page locally : all the data and code are in the page file.

I made some measurements and found that IE 6.0 was 5 times slower than
Mozilla 1.7. I made some changes
to the code and now the speeds are comparable. (No I did not put in
noops for Mozilla ;-)

Turns out that IE does not like appending to very large strings. In
developing the tables I would do a bunch of
appends for each row, with tracing I could see IE slow down as the table
got bigger. By building each row
separately and doing just one append per row, I got a five fold speed
improvement on IE. Mozilla still runs at
its old speed.

There are now just over 1000 patents in the list. It is definitely time
to set up a database....

Yes PHP is the way to go ;-)
