Frequent Redis Requests from Post Views Counter Plugin Causing Performance Issue

Dear Post Views Counter Support Team,

I am writing to seek assistance regarding an issue we are experiencing with the Post Views Counter plugin on our website. Our server team has identified that the plugin is making frequent requests to Redis, which appears to be overloading the cache and causing performance issues, including occasional downtime. Below are some specific details regarding the errors encountered:

[Wed Sep 04 11:35:08.820303 2024] [proxy_fcgi:error] [pid 2606133:tid 127777716045504] [client 162.158.154.141:24232] AH01071: Got error 'PHP message: RedisException: socket error on read socket in /var/www/html/wp-content/object-cache.php:560
[Wed Sep 04 06:06:21.493693 2024] [proxy_fcgi:error] [pid 2925720:tid 127777370015424] [client 162.158.63.130:51030] AH01071: Got error 'PHP message: RedisException: read error on connection to /run/redis/redis-server.sock in /var/www/html/wp-content/object-cache.php:1986...

Based on our analysis, it appears that the high volume of reads and writes to the Redis cache, particularly during peak usage times, is causing Redis to become overwhelmed. This issue seems to be exacerbated by the plugin’s behavior, which may be generating a burst of Redis operations, impacting the stability and performance of our website.

To address this issue, we would greatly appreciate your guidance on the following:

1. Optimizing Redis Usage: Are there specific settings or recommendations within the Post Views Counter plugin to reduce the frequency of cache access or to batch/cache operations more efficiently?
2. Configuration Adjustments: Are there specific Redis configurations or plugin settings that we can adjust to handle the high volume of requests without overwhelming the server?
3. Best Practices: Any best practices for using the Post Views Counter with Redis caching that can help alleviate the load?

We appreciate any insights or adjustments you can suggest to optimize the plugin’s interaction with Redis, as maintaining the stability and performance of our website is critical.

Thank you for your prompt attention to this matter. Please let us know if you need any further information or access to logs to assist in diagnosing the issue.

Best regards,
