In the world of legal, speed is of the essence. But all too often, lawyers are frustrated by sluggish case management systems that eat into their billable hours.
Bulky applications like Proclaim and Visualfiles are excellent tools for managing legal work, but they place high demands on your IT as they require little to no network latency to operate well.
These systems rely on Progress DB, which necessitates quick and reliable access to data to function at its best. Without this, the applications can become slow or unresponsive.
Just like a car runs smoothly with a well-tuned engine, these applications require a well optimised cloud environment to achieve peak performance and allow your lawyers to do their best work.
Why do these applications suffer from latency?
Progress DB is a robust and powerful database system that is used in various applications, including latency-sensitive applications like Proclaim and Visualfiles.
Progress DB is particularly sensitive to latency because of how it handles data transactions and communication between the database and application layers. Unlike some modern databases that are designed with cloud environments in mind, Progress DB was originally developed for on-premises infrastructure where network latency is typically negligible.
In a cloud environment, where data has to travel across various network layers and potentially across large geographical distances, even small delays can accumulate, leading to noticeable slowdowns in performance. This is especially problematic for law firms where every second counts.
The nature of legal work means that your CMS must be responsive at all times, whether it’s retrieving a client file during a meeting or processing a high volume of cases. This is why many law firms are hesitant to move their Progress DB-powered applications to Azure, fearing that potential latency could hinder their operations. But it doesn’t have to be this way.
Can apps like Proclaim work in Azure?
The answer is a resounding yes. Microsoft Azure, with its robust infrastructure and extensive capabilities, is well-equipped to host and manage these applications. However, it’s not just about making these applications work; it’s about optimising them to ensure they deliver the best performance.
With the right strategies and a deep understanding of how to optimize Azure for these applications, you can mitigate these concerns and even improve performance over traditional on-premises setups.
Here are six practical and effective ways to enhance the performance of your legal applications in Azure.
Six ways to speed up latency-sensitive apps in Azure
-
Choose the right Azure region
This might sound pretty obvious, but people don’t always think of it – you need to choose the right region for your services.
One of the most fundamental yet often overlooked factors in minimising latency is selecting the appropriate Azure location.
There are lots of regions to choose from, and it’s always best to select one that is closest to your end users, your head office, or the particular staff who are going to use the application. Or perhaps your own customers are going to access the application.
Where are they located? Do you have multiple sites or user groups?
The closer your services are to the users, the lower the latency. This can dramatically improve the performance of your applications, especially for those heavily accessed or latency-sensitive. So it’s worth getting right.
-
Enable Accelerated Networking
This is another one that’s commonly overlooked. Accelerated Networking reduces the latency on all applications and systems that use the enhanced adapters in Azure.
It bypasses the virtual switch and connects directly to the Azure backbone, cutting down on the processing time required for network traffic.
If you’re experiencing higher latency or suboptimal throughput with your virtual machines, Accelerated Networking can be a game-changer, shaving off precious milliseconds and improving overall performance.
-
Optimise disk performance
Disk performance is another critical aspect that can influence the latency of your apps, and it’s something you can optimise by simply choosing better-equipped hardware.
With Azure you can select from a variety of disk SKUs, each having different performance abilities. You can get your applications performing optimally without bottlenecks if you pick the right one.
These days, all but the coldest of data storage is done on SSDs – solid state drives. Without any moving parts (as traditional hard disks have), they’re already quite speedy, and for most application servers, we’d advise opting for SSD or Premium SSD.
For applications that need ultra-low latency, you might consider using Premium SSD V2 or Ultra SSD, which offer NVMe-level performance. They’ll have super, super low response times.
There is usually a cost trade-off with these – the high performers are usually priced a bit higher – but in many cases it’s absolutely worth it.

Utilise availability zones
Here’s another location related one. Azure operates in multiple regions, which contain different Availability Zones. Each zone is a separate physical location within the Azure region, often comprising multiple data centres.
Placing your resources within the same Availability Zone helps minimise latency, as the traffic doesn’t need to traverse different zones.
So for instance, if your Progress DB server and Azure Virtual Desktop (AVD) environment are in different zones, you might experience slower application performance. This is because you’re adding the time it takes for traffic to traverse from one Availability Zone to another to reach your application server and retrieve data.
So keeping them in the same zone can speed things up nicely, especially for certain database systems which have higher latency-sensitivity than others.
-
Make use of Proximity Placement Groups
Now, because an Availability Zone can span multiple data centres, we use something called Proximity Placement Groups (PPGs). PPGs ensure that your resources are physically close to each other by placing them in the same data centre.
This is particularly useful when you have multiple virtual machines, availability sets, or other resources that need to communicate frequently. When you reduce the physical distance between your resources like this, you get better throughput and latency. Shorter distances = faster speeds. Simple!
-
Implement ExpressRoute
Finally, we’ve got a less commonly-known option for reducing lag times.
ExpressRoute is an advanced networking option that provides a private connection between your on-premises networks and Azure.
From a customer’s environment – where they might have, say, a network or an MPLS – getting an ExpressRoute to take that traffic directly into Azure can save several milliseconds.
In our experience, we typically see a reduction of around 10 milliseconds in terms of round-trip time – that’s no small amount. For applications where every millisecond is crucial, this can make a significant difference.
Final thoughts
So now you have six solid ways to shave off those precious milliseconds and keep your Azure apps running without delays.
It’s all about making smart choices, whether it’s picking the right region, tweaking your networking, or optimising your disk setup. These are practical steps that can make a real difference to your app’s performance and, let’s be honest, your sanity when things get busy.
