The London Internet Exchange (Linx) has announced that the internet traffic it handles will pass the 25Gbps milestone just after Christmas, the equivalent of 1.5 million emails per second.
The level of traffic is more than twice that of 12 months ago, and the take-up of broadband in the UK is expected to boost traffic even further.
Linx said that traffic peaked at 22Gbps on 21 November, and the company is preparing itself for another traffic boom following the seasonal slowdown.
Chief executive John Soutar said: "Traffic definitely drops at Christmas, and picks up pretty steeply afterwards."
Linx handles up to 96 per cent of the UK's internet traffic, which is mainly made up of downloaded images rather than email.
It explained that more than 40,000 world internet routes, around 50 per cent of the global total, can be accessed through its exchange, which Linx claims makes it the largest and most important internet exchange point outside the US.
More than 14,600 routes from Linx (34 per cent of the total) are to UK and other European destinations, compared with just under 13,000 (30 per cent) going to North America.
This is important, according to Soutar, because it means less chance of UK traffic being slowed down by being routed across the Atlantic and back again.
"It is [a matter of] efficiency," he said. "If every time you surfed, your traffic popped across to New York and back, you'd soon notice."
Linx also revealed where the UK's internet traffic is coming from and going to.
Asian countries account for 22 per cent of Linx connected routes, with Oceania accounting for seven per cent and South America three per cent. The whole of Africa accounts for less than one per cent.
The US still accounts for the largest number of Linx routes at around 11,000, or 25 per cent of the total.
Internal routes within the UK account for only 4.4 per cent of the connections, fourth behind the US, The Netherlands and Japan.
