Angular6

Is there any performances issue while taking multiple child components in parent component. for each child component there is form builder.

What I have tried:

<form [formGroup]="form" ngClass="request-custom-form">
<mat-expansion-panel>
<dynamicform></dynamicform>
</mat-expansion-panel>
<mat-expansion-panel>
<dynamicform></dynamicform>
</mat-expansion-panel>
</form>
