Setting Network Package Size server option for best performance

Είναι γνωστό ότι οι λεπτομέρειες κάνουν τον πρωταθλητή και σε αυτό δεν νομίζω ότι έχει κάνεις αντίρρηση.

Ένα tip το οποίο μπορώ να δώσω σήμερα για τον SQL Server μπορεί να είναι μια μικρή λεπτομέρεια που όμως μπορεί να εξακοντίσει το performance του SQL Server στα ουράνια.

Ένα από τα advanced options του SQL Server είναι το Network Packet Size το οποίο by default είναι στα 4096 bytes.

Εάν έχω ένα instance που έχει μεγάλο όγκο από bulk operations ή μεταφέρει μεγάλο όγκο δεδομένων, και αν υποστηρίζονται και είναι ενεργοποιημένα τα jumbo frames στην κάρτα του server και στο δίκτυο, και δεν έχω αλλάξει την τιμή σε 8192 τότε κακό του κεφαλιού μου!!!
