السلام عليكم
كيف الحال يا اخوان
لدي مشكلة في اللود العالي على السيرفر
وبعد الاستعلام والبحث اتضح ان المشكلة حدثت بعد نقل قاعدة البيانات على سيرفر جديد
هل هناك شركة معينة اجنبية او عربية ينصح بها وتستطيع ان تخدمني في تصحيح تلك الاخطاء
ايضا قمت بالاستعلام بواسطة mysqltuner
وكانت النتيجة

-------- Recommendations -----------------------------------------------------
General recommendations:
Add skip-innodb to MySQL configuration to disable InnoDB
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Adjust your join queries to always utilize indexes
Increase table_cache gradually to avoid file descriptor limits
Optimize queries and/or use InnoDB to reduce lock wait
Variables to adjust:
query_cache_size (> 48M)
join_buffer_size (> 8.0K, or always use indexes with joins)
table_cache (> 512)
لاحظت ان هناك مشكلة Maximum possible memory usage: 2.3G (28% of installed RAM)
ماهي الطريقة الصحيحة لزيادة قدرة المومري حيث ان هناك 8 رامات على السيرفر وموقع واحد بقاعدة بيانات واحدة والمومري لايتعدى 30% رغم ان اللود يصل الى 79.59 (4 cpus)
