Hello, For now, I'm trying to evaluate the performance of memcached server by using several client workloads. I have a question about multi-get implementation in binary protocol. As I know, in ascii protocol, we can send multiple keys in a single request packet to implement multi-get.
But, in a binary protocol, it seems that we should send multiple request packets (one request packet per key) to implement multi-get. Even though we send multiple getQ, then sends get for the last key, we only can save the number of response packets only for cache miss. If I understand correctly, multi-get in binary protocol cannot reduce the number of request packets, and it also cannot reduce the number of response packets if hit-ratio is very high (like 99% get hit). If the performance bottleneck is on the network side not on the CPU, I think reducing the number of packets is still very important, but I don't understand why the binary protocol doesn't care about this. I missed something? Thanks in advance, Byungchul. -- --- You received this message because you are subscribed to the Google Groups "memcached" group.
