مشکل در کوئری*های زیاد و طولانی

سلام دوستان
چند روی هست که سرویس دهنده هاست گزارش*هایی مبنی بر تعداد بالای کوئری*ها که هر کوئری هم بین ۳ تا ۴ ثانیه طول میکشه برای ما می*فرسته که همین امر باعث فشار به سی*پی*یو سرور میشه
من بیشتر ماژول*ها رو غیر فعال کردم اما هیچ تاثیری نداشت
و ظاهرا ربطی هم به بازدید نداره، چون سرویس دهنه میگه این موضو دائم هست و زمان خاصی نداره
خودشون میگن بیشترین کوئری مربوط به

components/com_contact/models/category.php
و
components/com_content/models/articles.php

هست که من این دو فایل رو حذف و جایگزین کردم اما تاثیری نداشت

از دیروز هم ایندکس سایت رو بستن و فقط قسمت مدیریت باز هست تا مشکل رو برطرف کنیم
من از جوملا ۲.۵.۸ و قالب shaper_simplicity_ii که رایگانه استفاده میکنم

اینم گزارش سرویس دهنده
