Janne Jalkanen commented on CASSANDRA-3551:
-------------------------------------------

1.0.5, RF 3.  I upgraded just recently directly from 0.6.13, so I have not been 
on any earlier 1.0.x version.  No compression, just a straightforward upgrade 
with minimal tuning to the cassandra.yaml file.  2GB heap, maybe ~1GB in use.  
Happens with column families which have 20 rows, CFs which have 10000 rows and 
more.  Happens when trying to read 100 rows at a time, happens when trying to 
read 10k rows at a time.  The only factor that I've noticed while trying to 
tune that has any effect is changing the CL.

No errors in node logs.
