Dear community,
is someone working on this ticket? This is clearly performance regression
and we stuck with 3.11.6 and could not upgrade to latest version.
Regards,
Maxim.

Hi folks,
If this can help, we encountered the same behaviour with 3.11.9. We are
using LCS.
After upgrading from 3.11.3 to 3.11.9 in Bench Environnement, Cassandra
read latency 99% is multiplied by ~3
We are planning a second test with 3.11.6, I'll send you the results when
it's done.
Cheers,
Any update on this? Any idea if this is already tracked under JIRA issue,
so we can follow for updates

Any update here? Does version 3.11.10 provide any improvement?
Thanks,

Hi,
I'm not sure if this will help, but I tried today to change one node to
3.11.9 from 3.11.6. We are NOT using TWCS. Very heavy read pattern, almost
no writes, with constant performance test load. Cassandra read latency 99%
increased significantly, but NOT on the node where I changed version
Thanks Paulo! I'll give it a try and let you know.

As a workaround if your TWCS table is
As a workaround if your TWCS table is append-only (no updates or deletions)
you could try enabling unsafe_aggressive_sstable_expiration (see
https://cassandra.apache.org/doc/latest/operating/compaction/twcs.html) so
inactive sstables will be expired faster and will not be included during
reads.
I think this could've been caused by
https://issues.apache.org/jira/browse/CASSANDRA-15690 which was introduced
on 3.11.7 and removed an optimization that may cause a correctness issue
when there are partition deletions. I'd suggest you to open an issue at
+1
I would also be interested to know if the 3.11.9 provide any improvement
for your case.
Cheers.

Have you (or others) any update on that? Does the version 3.11.9
released today
uld be interested
to see your results too.

Maybe compare the cache size see if anything different in two versions?
