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

Hi,
thanks for your interests!
We use TWCS and LCS and see only TWCS effected by the update regarding higher
latencies (as we
. I'll let you know about the results.

Hello Nicola
Hello Nicolai,
I am also looking to upgrade to 3.11.8. Is the latency you noticed is only
with TWCS? And others looks good?

I would also be interested to know if the 3.11.9 provide any improvement
for your case.

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?

Dear Cassandra community,
after upgrading my Cassandra nodes from version 3.11.6 to either 3.11.7 or
3.11.8 I experience a significant increase in read latency.
With 3.11.6 average read latency is ~0.35 ms. With 3.11.7 average read
latency increases to ~2.9 ms, almost 10 times worse! This
