You must be blind. You wrote:

Check the proper format of a GeneralizedTime value. You have omitted
the seconds field, so you're effectively looking for every entry
greater than the year 20, December 09. The index lookup for this will
most likely hit every entry in your DB, which is why it takes 57 seconds.
thanks for suggestion. Apologies for my extra curiosity.
I tried full GeneralizedTime format (with seconds, with fractions) but
the search works also slow.
Even the search
that works less than second and returns 2 entries, when reformatted as
works more than 50 seconds.
According to RFC4517 (
), GeneraalizedTime has
GeneralizedTime = century year month day hour
[ minute [ second / leap-second ] ]
[ fraction ]
which means that minutes and seconds may be omitted. Probably that's not
implemented... no problem.

How may I optimize (&(>=)(<=)) searches?
