Note: Split off from here.
I’m also having this problem. I have 2 EE2 installations on my server and this is what I’m experiencing:
1. Installation #1 on 2.1.0 with just a few hundred records works fine
2. Installation #2 on 2.1.3 has the same problem as specified by the original poster on the channel that contains over 10,000 records. (worked fine until recently on EE1)
3. Installation #2 works fine on channels that have a few records.
4. Installation #2 is very slow on the front end on pages that access the channel with over 10,000 records.
Seems that this is an issue with EE2 (regardless of version) with channels that have a lot of data. Increasing the PHP memory limit is a bandaid that could cause server problems during times of high traffic. I’d rather get to the bottom of the actual issue. Any insights?
