GM_deleteValue Slow

[TimidScript]

If you have a large database and you remove values from it, the process is very very slow and it can hang Firefox if the data content is large. Do you do a compact operation with each delete?

I do not see why the process is so slow.. It's not so bad when adding new large data. Removing or replacing existing data is painfully slow.

Can you be more objective than "very slow"? How many milliseconds does it take? How many would be few enough to no longer be "too slow"?

I would add an index on the 'name' field.

I no longer have the script but I remember it was in seconds and not ms. The number of records in the database was in the thousands and some records were pretty large.

After adding this line to GM_[gs]etValue_Bench.user.js:
measure('delete', GM_deleteValue, n);

I propose to close this issue.

Agreed, this performs reasonably for me after fixing #2197.
