There is overhead on Redis 7.0 EXPIRE command that is not present on 6.2.7. We could see that on the unstable profile there are around 7% of CPU cycles spent on rewriteClientCommandVector that are not present on 6.2.7. This was introduced in #8474. This PR reduces the overhead by using 2X rewriteClientCommandArgument instead of rewriteClientCommandVector. In this scenario rewriteClientCommandVector creates 4 arguments. the above usage of rewriteClientCommandArgument reduces the overhead in half. This PR should also improve PEXPIREAT performance by avoiding at all rewriteClientCommandArgument usage. Co-authored-by:
