The maximum number of connections MySQL can support depends on the quality of the thread library on a given platform, the amount of RAM available, how much RAM is used for each connection, the workload from each connection, and the desired response time. Increasing open-files-limit may be necessary. Also see Section 2.5, 鈥淚nstalling MySQL on Linux鈥? for how to raise the operating system limit on how many handles can be used by MySQL.
