MySQL sun v240 performance
Hi,

we are having one sun v240 server, now this server is performing very slow,
checked using top, iostat and vmstat commands, output is looking normal, but the performance is very slow and generating more traffic in network,
how can we resolve this.

Regards
RJS

You have 68 zombie process in your server which causes the performance degrade. Please kill all these processes and check if becomes normal.

Thanks,

While a zombie process is something to investigate, it cannot cause any performance issue as it uses no resources.

A zombie (a.k.a. defunct) process can't be killed as it is already dead. If the parent process doesn't properly handle the situation, It can be reaped with the preap command.
