I have created a time tracking app which captures every minute activity of 400 people.
Means if no one query my database I still have 400 insert request to MySQL every minute.
Everything working fine till now but then I have to give the user a dashboard where they can see every entry of their tracked time.
Now I have 400 people querying my database, after launching query page the system becomes very slow, Disk usage go to 100% much time. I'm planning to deploy more apps on the server but before moving forward I want to solve this problem.
I'm thinking of changing my hard disk from HHD to SSD to increase read-write speed but wondering If there are any settings I can tweak in my default my.ini file to get better MySQL performance
Below is the my.ini file I have modified with the help of my-innodb-heavy-4G.ini my PC running MySQL 10.1.36-MariaDB,64bit, 3.60GHz, i7 with 8 GB RAM.
I just wanted to know if the below settings are correct or not. I don't want my server to crash and stop working. Please help me in addition or deletion of any setting line which can cause an issue.

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted server-id = 1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended
