The company regularly every day network card problem-CodePudding

our company's network has recently been a network card, open the web site is slow, often can't open need to refresh many times to open, especially at half past eight to nine o 'clock in the morning this time, because this time is the peak time of our company use the Internet, basic brush all employees will be web pages, use the number at more than 40 desktop computer, combined with their own mobile phones,
Haven't seen this problem before, just like that every day recently,
Thought it was equipment and bandwidth issues, so in the new gigabit router and gigabit switches, at the same time the speed from 200 m to 500 m, had just finished upgrading the network is process of a few days, over the years began to appear this problem again,
Could you tell me the great spirit, this problem will appear in which aspects?? Will there be may be under attack?
The following figure is the background of IP traffic statistics, looks very normal??
