buffer ni reset qilmasdan, default size bilan saqlab qo'ygan yaxshimasmi?

@Dostonlv manimcha normalniy, shu faqat default size bilan saqlaganiz yaxshi poolga

adashdim, xullas, saqlashdan oldin Reset qilish kerak

 buf := bufferPool.Get().(*bytes.Buffer)
 defer bufferPool.Put(buf)
 defer buf.Reset()

mana shunaqa qilsez bo'ladi
