Sometimes slowness observed, in retrieving object from Azure Redis cache with key of pattern "http:____my.website.com", whereas time to retrieve object with key "abc_xyz_def_test_test" is almost consistent no spike in retrieving time like in other case mentioned. Size of the both the objects stored against "http:____my.website.com" (or) "abc_xyz_def_test_test" are of almost same. Also verified serializing the object to custom type, not playing foul here.
Is the slowness because of the key pattern? Please clarify. Also how to overcome this slowness issue.
Azure redis P1 tier (without cluster) used in this case. Redis metrics like CPU/Memory are normal as shown in Azure portal.
