Set up on the basis of copies of the original web server of the web cluster Bitrix instructions
. 4 VDS servers: mgmt+web, db master, db slave, memcache. Each server is 8 GB + 4x2,4 GHz + SSD (TimeWeb). Timings between servers minimum, all servers are tuned for maximum performance, the storage of temporary tables in the database not in memory. Panel performance (see image 1) gives no comforting results.
On the original server where all services in one place, the results were much better (see picture 2).
What could be the reason for such bad results?
