Currently i am using memecache, but facing some speed issue and longer SQL queries issues in my classified. And now i want to implement the redis cache into osclass website maybe it will help a lot in reducing the speed and load times, also it will improve SQL performance as well.

There should be support for that in 8.1.1 but I think it was not well tested and could not be debugged for possible issues.

i am getting this error when I enable redis caching, and also HTTP ERROR 500 many time while loading any page.
 my php 8.1 and osclass 8.1.1
