If you’re running a business in 2025, the question isn’t whether you need fast internet anymore. The question is whether your current connection can keep pace with where your business is actually heading. For many companies still operating on 1Gb leased lines, the answer is increasingly becoming “no.”
The good news? Upgrading to 10Gb capacity has never been more accessible. Prices have dropped dramatically over the past few years, and the performance gap between 1Gb and 10Gb isn’t just incremental—it’s transformational.
Let’s be practical. When we talk about 10Gb leased lines, we’re not just discussing a number that’s ten times bigger. We’re talking about fundamentally different operational capabilities for your business.
A 1Gb connection transfers roughly 125 megabytes per second. That sounds impressive until you consider what modern businesses actually do:
• Video conferencing across multiple teams simultaneously – Each 4K conference call consumes 15-25 Mbps. With remote and hybrid working now standard, you might have 10, 20, or 30 calls happening at once.
• Cloud backup and synchronization – Modern businesses backup terabytes, not gigabytes. On a 1Gb line, backing up just 1TB takes over two hours. On 10Gb, it’s done in 13 minutes.
• Large file transfers – Whether it’s CAD designs, video production files, medical imaging, or software builds, professional files have exploded in size. A 50GB project file that takes 6.5 minutes on 10Gb would take over an hour on 1Gb.
• Real-time collaboration – Design teams using Figma, engineering teams with live development environments, finance teams with real-time analytics—these aren’t future scenarios. They’re happening right now in your business.
One of the most significant developments in recent years is the availability of flexible contention ratios for 10Gb services. This is where the economics become genuinely interesting for businesses currently on 1Gb.
What is a Contention Ratio?
Traditional 1Gb leased lines offer a 1:1 contention ratio—you get dedicated, unshared bandwidth. But with 10Gb infrastructure now widespread, providers can offer more flexible options that dramatically reduce costs while still delivering exceptional performance.
Here’s how it works:
You’re guaranteed at least 5Gb of bandwidth at all times, with burst capability up to 10Gb. In practice, most businesses will experience near-full 10Gb speeds most of the time because your usage patterns rarely align perfectly with the one other connection sharing your capacity.
Real-world impact: Even at minimum guaranteed speeds, you’re operating at 5 times your current 1Gb capacity—and typically much higher.
Your guaranteed minimum is 2Gb, with burst capacity to 10Gb. For most businesses, average realized speeds will be 6-8Gb throughout the day.
Real-world impact: Your “worst case scenario” is double your current capacity, while typical performance is 6-8 times faster.
Guaranteed minimum of 1Gb, bursting to 10Gb. This might sound similar to your current service, but there’s a critical difference: your baseline matches your current maximum, while you gain enormous headroom for growth and peak demand.
Real-world impact: You maintain current baseline performance while gaining burst capacity that transforms how you handle peak loads, large transfers, and concurrent demands.
For IT managers, this is significant because overprovisioning is now affordable. Rather than constantly managing bandwidth scarcity, you can finally architect for abundance. And for finance directors, the message is equally clear: these options deliver 10Gb infrastructure economics that often rival what you’re currently paying for 1Gb.
Direct Comparison: 1Gb vs 10Gb Performance
Let’s compare real business scenarios:
Your situation: Monthly all-hands meeting with 200 employees across 8 offices, plus daily team standups
• Video quality automatically degrades to 720p or lower
• Screen sharing becomes choppy
• Some users report audio cutting out
• IT receives complaints after every large meetingEmployees join from personal devices on mobile data to ensure reliability
• All users maintain 1080p, with 4K available for key presenters
• Screen sharing is seamless, even with animation-heavy slides
• Concurrent breakout rooms don’t impact quality
• Recording and streaming happen without affecting participant experience .Your unified communications platform performs as designed
Your situation: You’ve migrated to Microsoft 365, Salesforce, and cloud-based design tools
• Opening large PowerPoint presentations from SharePoint takes noticeable time
• Salesforce reports with extensive data load slowly
• AutoCAD or Revit cloud collaboration experiences lag
• Cloud rendering queues up rather than processes in real-time
• End-of-month close takes longer due to system responsiveness
• Applications respond as if they’re installed locally
• Large dataset manipulations happen in real-time
• Multiple teams can pull extensive reports simultaneously
• Cloud rendering processes immediately
• Your cloud investment delivers its full ROI
Your situation: Nightly backups, disaster recovery replication, and compliance requirements
• Backup windows extend into business hours
• Incremental backups are prioritized, full backups happen monthly
• DR testing is scheduled carefully to avoid impact
• Backup traffic competes with production workloads in early morning
• Full backups complete in fraction of the time
• Continuous data protection becomes viable
• DR replication happens in real-time
• Backup traffic is negligible compared to available capacity
• Compliance requirements are easier to meet
