What machine size?
m1.large
If you are seeing high CPU move to an m1.xlarge, that's the sweet spot.
That's normally ok. How many are waiting?
I have seen 4 this morning
That's not really abnormal.
The pending task count goes when when a file *may* be eligible for compaction,
not when
Thank you very much! Due to monetary limitations I will keep the m1.large
for now, but try the throughput modification.

During repair I see high CPU consumption,
Repair reads the data and computes a hash, this is a CPU intensive operation.
Is the CPU over loaded or is just under load?
I run Cassandra version 1.0.11, on 3 node setup on EC2 instances.
What machine size?
there are compactions waiting.
That's
