I am using a MySQL database with around 300-500 connections at the same time. I am hosting this on a Ubuntu 18.04, 8 GB Dedicated RAM, 4 CPU, 140GB SSD server. My database is not huge but I am running into issues and would like to consult with an database (mysql) expert to help me fix the problem, or understand if I need to upgrade the server resources.

hi! I don0t think you need to upgrade your server, or at least to be sure we must look @ MySQL logs. Of course, we need also to look @ memory and heap settings of your MySQL installation. I just need ssh credentials for your MySQL box. I can start immediately.

Hi, Can you provide the queries in question and access to a replica of the database? Do you currently have indexing on the tables? If you can provide the scripts that are calling the queries those would likely be optimized.

Hi There, I am a developer having more than 10yrs of experience in making heavy load websites and fine tuning mysql server. Slow query can be result of multiple issues and it can be at server/hardware or software level. Exact reason can be traced out only after monitoring server loads and logs. I can figure out issues and provide solution if you allow me to do so.
