Fixed the performance degradation in the wips workload of the TPC-W benchmark. The global variable is used to record the state of the page buffer. And when calling the pgbuf_fix() function, etc., this global variable is increased. As a result, performance degradation of about 150 TPS occurred. It was identified as a problem caused by several threads competing for one global variable. Therefore, I have resolved this problem.
