This version is exceedingly slow

[pensionado]

Yesterday I used this version for my daily updates, and these are the summary statistics:
2017-02-23 07:13:51 : Verzamel statistieken van 1721 programma's voor 16 zenders:
2017-02-23 07:13:51 : Start tijd: 2017-02-23 06:52

2017-02-23 07:13:51 : 84 pagina('s) opgehaald van theTVDB.com
Today I ran the 2.2 version again and these are the summary stattistics:
2017-02-24 06:46:55 : Fetch statistics for 1606 programms on 16 channels:
2017-02-24 06:46:55 : Start time: 2017-02-24 06:45
2017-02-24 06:46:55 : End time: 2017-02-24 06:46
2017-02-24 06:46:55 : Duration: 0:01:53.098212
2017-02-24 06:46:55 : 107 page(s) fetched, of which 0 failed
2017-02-24 06:46:55 : 564 cache hits
2017-02-24 06:46:55 : 10 succesful ttvdb.com lookups
2017-02-24 06:46:55 : 8 failed ttvdb.com lookups
2017-02-24 06:46:55 : Time/fetch: 1.05699263551 seconds

So looks like this version needs 20 times more elapsed for roughly the same number of pages. Will stay on 2.2 until this version is indeed faster / comparable to 2.2

Yes it is slower, but you are also not properly comparing. Once you use it for a week it will get faster as the database starts filling up. Also if you compare correctly it does 20 times more ttvdb lookups, it finds 7% more programmes, etc. etc. Also it is 11 times slower in these two runs (11,28 sec /page and 1,05 sec/page) and not 20!

Secondly you have, especially if you use TVheadend the --use-only-cache option, which is blitzingly fast, for direct access, letting the actual fetching run, run at night at leasure!
