oop issue with vps server

Job ID: 32457768

Budget: $30 – $250 USD

we got a very strong vps server to run our web game that is based on oop
the game is about wars ,each player supposed to make attack tasks and each task has store in db with values execution time and type

if execution time = now , then the query will be auto fired by the system

the normal tasks num per hour is 3000-5000 tasks .

our issue is the following :

we there are 100+ tasks in queue that supposed to end at one time ,then instead of execution all. of them at once , the server is doing them one by one , which makes the tasks loaoded and take more time to execution

and. the game is mainly depending on timing , can not afford delay

the cpu and ram both are below 30% usage

the game is built with pdo , in oop clases

any ideas how to fix ?
