It has helped us improve our latency performance drastically
As a large scale high performance trading platform serving the high frequency trading community, latency has always been critical for our clients. Before using Azul Zing JVM, we would have had to spend a lot of effort tuning our JVM GC and profiling our application to minimize latency, which is…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"With minimal effort, Zing has helped us improve our latency performance dramatically."
"GC Pause times are maintained in low milliseconds, which is beneficial for applications with high volume, high memory allocation rate, and a high memory footprint, and it also increases throughput by approximately 20-25% as compared to Oracle Java Development Kit based on some tests that I have done with real applications."
"No other JVM on the market even comes close to competing with the Azul Zing."
"Zing has completely solved the garbage collection problem for us."
"The non-stop garbage collector (C4 - Continuously Concurrent Compacting Collector) is the most valuable feature."
"With Zing, we've now been able to re-allocate those tuning resources to general product development."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."
"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."
"We've had no issues with stability."
 

Cons

"The profiling tools included with Zing lag behind those available for Oracle's Java implementation."
"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"We have encounter stability issues and that has been a source of frustration at times."
"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"The licensing over non-production environments considerably affects the cost of our solution as a software vendor."
"It is extremely expensive."
"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."
"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."
