How to estimate the L2 shared memory usage on Ubuntu

ms flag

I'm trying to improve the performance of one of our systems and I'm supposing that the bottleneck resides on the L2 shared memory of my CPU.

Thus, I'm looking for a way to estimate how much of my CPU shared memory it is actually being used during the perf tests.

I tried to find something useful on top manpage here with no success.

*Why* do you suppose that the issue is the L2 cache?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
