I have installed RO CSVI 8.9.2 with the additional Virtuemart and other plugin's. Unfortunately the process is extremely slow. For importing 64 products the last server response exceeded 300. Ultimately the process was completed but the release is useless.
I returned to RO CSVI 8.9.1 and everything is back to normal.
Virtuemart is on 4.2.4.
Please advice.
