Hi,
Thank you for your reply. Guess you didn’t read through my questions. We have configured Redis and using it already from almost 10-12months and It was working fine.
Recently, from last one week we are seeing spike in redis usage which is all most 100% and earlier redis usage was at 40-50% in an average. Since redis usage is 100% and traffic is being redirected to the servers now and its stressing the servers. With this additional background, let me re-phrase my questions or ask again:
- We need to understand from W3TC: If redis page cache keys are created based on the visitor traffic to the site? ex if we have post a,b,c,d: for each site visitor different page cache keys are created for individual posts?
- How we can plan the capacity of the redis caching servers? currently we are using Cloud managed service. Is there any formula?
- What might be the reason for suddenly redis servers are being utilized 100% where is there is no changes on the site.
Please let us know if any additional info is needed also is there any dedicated support from W3TC? We have 2 Pro licenses for different environments.
Looking forward for the answers.
Thanks in advance.
