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 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 drastically."
"The non-stop garbage collector (C4 - Continuously Concurrent Compacting Collector) is the most valuable feature."
"Zing has completely solved the garbage collection problem for us."
"Performance of the JVM, especially the C4 Pauseless Garbage Collection, for continuous application execution is the most valuable feature."
"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."
"With minimal effort, Zing has helped us improve our latency performance dramatically."
"The fact that it is available open-source is the best feature."
"The Zend Framework provides an easy, open source way to produce coding based on the needs of our customers.​"
"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."
"Zend PHP Engine is more secure than any other framework, and I usually prefer Zend PHP Engine for big applications."
"The most valuable feature of this solution is the speed at which it compiles and sends the dynamic cache."
"It makes web design easy and quick and gives well finished websites."
"Scaling up is an important factor for large projects, and with PHP 7 and its performance improvements, this becomes even easier.​"
"This solution is really easy for me to use."
 

Cons

"Although Azul claims to have a fast warmup, we still experience higher latency for the first trade when our system starts up on Sundays."
"However, like every other great product, there is always something that can be improved."
"The licensing over non-production environments considerably affects the cost of our solution as a software vendor."
"It is extremely expensive."
"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 profiling tools included with Zing lag behind those available for Oracle's Java implementation."
"We have encounter stability issues and that has been a source of frustration at times."
"A general scripting language should be further developed and should be embedded into it."
"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM.​​"
"The process of installing and configuring the product is a bit complex and could be improved."
"The platform is not satisfying to me -- it is just not up to standards performance wise."
"Zend PHP Engine needs to improve the loading time of its libraries and make it faster."
"Although it offers a complete environment to develop and deploy PHP applications, it has some limitations. For example, when the volume of data increased exponentially, I had problems scaling the system."
"Integrating AI tools would make PHP more competitive, as other tools already have AI features."
"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."
 

Pricing and Cost Advice

Information not available
"Its pricing depends on the number of users."
"The solution is open source and you just pay for the server cost."

"Zend PHP Engine is not an expensive solution."
"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."
