The performance of the project has been at the lower-and lower-level and has been exploring. Since the WCF segment was optimized in the past few weeks, the speed has improved significantly.

Situation Some time ago, we found that multiple clients frequently obtain the same data when they connect to the server for the first time. That is to say, each client needs to search for the same data in the
