PHP - MSSQL configurations cause slow performance [closed]

manpreet Best Answer 2 years ago

I have a problem in my project using PHP and MSSQL. I have the following configurations:

64 GB Ram 16 CPU Intel Xeon SQL Server 16 GB Ram 4 CPU Intel Xeon Web Server

And I have the following code:

 SELECT 
     protokol.hekim_tc as hekim_tc,
     iller.il_adi as il_adi,
     SUM(protokol.taniveilacolan)as taniveilacolan,
     SUM(protokol.taniolanilacolmayan) as taniolanilacolmayan,
     SUM(protokol.taniveilacolan+protokol.taniolanilacolmayan) as protokolsayisi,
     SUM(protokol.antibiyotik_yazilan) as antibiyotik_yazilan,
     SUM(protokol.agrikesici_yazilan) as agrikesici_yazilan,
     SUM(protokol.enj_yazilan) as agrikesici_yazilan,
     SUM(protokol.enj_agrikesici_yazilan) as enj_agrikesici_yazilan,
     SUM(protokol.antibiyotik_yazilan) as antibiyotik_yazilan,
     SUM(protokol.enj_antibiyotik_yazilan) as enj_antibiyotik_yazilan,
     kalem_sayisi,
     kutu_sayisi,
     maliyet
 FROM rdp_2013_protokol_dagilimi_copy2 AS protokol
 LEFT JOIN iller ON iller.il_kodu = protokol.hekim_il
 LEFT JOIN (
     SELECT hekim_tc, 
     SUM(kalem_sayisi) as kalem_sayisi, 
     SUM(kutu_sayisi) as kutu_sayisi, 
     SUM(maliyet) as maliyet
     FROM rdp_2013_atc_dagilimi
     GROUP BY hekim_tc
     ) AS atc
 ON atc.hekim_tc = protokol.hekim_tc
 GROUP BY
     protokol.hekim_tc,
     iller.il_adi,
     kalem_sayisi,
     kutu_sayisi,
     maliyet

The problem is that the query above lasts only 6 sec. in SQL Server. But when I run the same code in PHP on IIS server, it lasts more than 5 minutes. Which configuration am I supposed to look for and change?
