Forge's heavy performance impact

[HealGea]

First off all I tried to find a fix for the problem but I couldnt,anyway I tried with minecraft 1.12.2 and lastest recommended version with optifine c7 no mods and with only optifine c7  as we can see in screen shots I take lower fps with forge but its a little bit confusing because when whenever I stop moving fps values come back the normal (still lower then only optifine version) but while moving heavy performance decreases,drops and stuttering is happening so I need help
