Finding bottleneck on my server

Dear All
feeling my server is sluggish with below specification on a dedicated server which seems to be slower than digital ocean’s USD20 package.

CPU : Intel(R) Atom™ CPU C2750 @ 2.40GHz
Ram 8GB
Core: 8

Checked the %iowait (IO) and %idle (CPU) which seems to be healthy. Also tuned mariaDB as below:

innodb_buffer_pool_size = 6G
innodb_buffer_pool_instances = 6
innodb_log_buffer_size = 8M
innodb_file_per_table = 1
innodb_open_files = 400
innodb_io_capacity = 400
innodb_flush_method = O_DIRECT
innodb_thread_concurrency = 0
innodb_read_io_threads = 8
innodb_write_io_threads = 8

are there something else i should be looking at? Thank you.

Are you sure it’s the server and not the bandwidth of the server? The specs look alright.

how to i measure that bandwidth info?

Try to download a big file off the server. Also ping the server. See if you’re dropping packets / ping is high.

Nah, it’s file. Did you check bandwidth?

downloading a 5G file off server, averaging 500KB/s , think thats fine?

Use htop - an interactive process viewer

@Jay try it when you are experiencing slugglish behaviour

That is a very underused server at the moment. Maybe you have network latency (?)

@Jay Yea, that’s not bad

@rmehta The latency is ~130, which isn’t terrible

ok will try it when server on heavy load,thank you for your time
