Hello Pan, I've updated the patch I attached yesterday with a change that caches the most-recent tgid search result. From ~70% to ~90% of the time, either the last tgid entry or the very next one in the tgid_array is the one being searched for, so it's not necessary to call bsearch() every time.
yes, you are right. I have not considered the problem which calling bsearch() every time. thank you very much.
"help -t" will show the cache-hit statistics. Thanks, Dave
