I test again and…..It’s ok. HaHaHa.
I don’t know why.
First test(Topic start) I use the machine with the mobile internet, 10 Mbps or less.
Second test (now) I use the machine with the home internet 900 Mbps or less.
Both tests, I test with many image and many extension.
I will test with the mobile internet again on Monday then inform you the result.
Thanks anyway.
