Version: 4.8 (using Devel)
If I have 1,500 contacts, Nepomuk will take more than 5 hours to index only the contacts, without any involvement of Strigi or deep indexing features. This with Virtuoso running at 100%.
Steps to Reproduce:
1. Add the Facebook resource and the Google Contacts resource.
2. Let them populate your Contacts, your Birthdays and your Events.
3. Run Nepomuk in an isolated setup (clean database, no Strigi indexing, no mail indexing) and Akonadi with at least the Facebook, Google, Birthdays and some mail resources (if available).
Nepomuk takes hours to index contacts.
Nepomuk takes a few minutes to index contacts.
Strigi isn't doing anything. CPU usage is more than 100% (2 cores). Also, nepomukstorage is consuming 200 MB of RAM and dbus-daemon is eating 160 MB of RAM, after indexing only contacts, with everything else disabled in Nepomuk.
This is quite telling.
After indexing contacts, memory usage figures are as follows.
nepomukstorage: 210,884 KB
dbus-daemon: 163,620 KB
virtuoso-t: 163,524 KB
akonadi_facebook_resource: 87,704 KB
akonadi_nepomuk_feeder: 82,972 KB.
