Why a simple effect RSS like this have to use 70mb of ram :/
Greetings,
I have about 300 channels and only 3 smartfeeds. Memory avarage usage 65-75 MB-
computer is (Celeron 1.8ghz + 512 mb) .
Currently I think, that we having performance issue on smartfeeds (performing unread counts).
If smartfeed is like body like 'something' or title like 'something', those smartfeeds are really slow (no indexes can be used) and drive CPU up to 99%.
Currently best method to keep FR fast, is to use "FeedReader Backup Utility"
once in a month, fix error, perform dbcleaning and full backup and restore.
Then Firebird indexes are recreated and you have more speed.
And for users who are more in IT, we would be very happy, if you could also test latest stable Firebird embedded server (v.2.0.3).

Firebird-2.0.3.12981-1_embed_win32.zip
ps unpack those DLL's into Feedreader30 dir and rename, fbembedded dll to fbclient.dll

If smartfeed is like body like 'something' or title like 'something', those smartfeeds are really slow (no indexes can be used) and drive CPU up to 99%. TRUE
but that is when you query all of the transactions and on daily basis you don't need that..
if you set a smartfeed
(query)Article Age 'Newer than 2 days'
(subquery) body like 'something'
(subquery) title like 'something'
the performance is very much improved

You are 100% correct !
But many users are not using this feature:(

Think about it as not that simple RSS + Internet Explorer engine+ Firebird SQL database engine that we must keep in our memory while running :).
I have 2 gigs of memory in my computer. I have heard that some guys even have 4 gigs ;). So it's not that big percentage of used memory.
My Experience
Hi,
I have 25 channels (Feed Sources) and 10+ SmartFeed in feed Reader. My datbase size is around 100MB. I daily delete older than 30 days articles. FeedReader takes 85MB memory when idle. It spikes to 100MB sometimes. And, I do have 4GB of memory. It's just fine for me.
On the contrary, I installed FR in a friend's eMachine (Celeron 2.xGHz + 1GB). He never deletes any articles, i think. He was complaining his PC is running really slow now a days.
