Recent reports from developers indicate significant delays in transaction processing using JavaScript-based gRPC implementations in decentralized exchanges (DEXs) like Pumpswap and Meteora DLMM. With the increasing volume of transactions, users are asking: why are these processing delays occurring, and what can be done to speed things up?
Developers linked to the DEX community are grappling with performance issues when handling large data sets from various exchanges. One developer pointed out that while their initial code handled transactions seamlessly, integrating pumpswap resulted in lag timesโtransactions becoming as outdated as 40 seconds before being processed.
"JavaScript is the bottleneck here," one user commented, highlighting the limitations of JS in CPU-heavy tasks.
Developers worldwide face similar challenges:
Single-threaded Execution: JavaScript operates primarily in a single-threaded environment. This poses issues when processing large datasets, causing bottlenecks as old transactions are prioritized over new ones.
Worker Threads Attempt: Some users experimented with worker threads but found limited success, reinforcing the frustrations felt within the community.
One developer expressed concern about transitioning to Rust, noting:
"Rebuilding this in Rust is a pain, especially since Iโm not familiar with it."
While transitioning languages may offer performance boosts, the learning curve remains a significant barrier for many.
The sentiment in the forums reflects a mix of frustration and hope:
Some users suggest alternatives like Python, where others have reported no issues with heavy processing.
Others emphasize deeper dives into JavaScript's architecture and performance enhancement techniques.
Several quotes from the user boards echo this concern:
"Best you can do is build it in something else."
"Some believe Rust may be the ultimate solution, but the uncertainty about facing the same challenges lingers."
Here's what the community is saying:
โ JavaScript Performance: Many agree JS isnโt suited for high-volume processing.
๐ Alternative Solutions: A shift to languages like Rust and Python is seen as a potential fix.
๐ Challenges Remain: Users report ongoing struggles even after attempting enhancements.
The processing delays in JavaScript for gRPC transactions are prompting discussions on the viability of the programming language for such intensive workloads. As the crypto space continues to expand, will developers adopt new languages, or will they find ways to optimize existing code? Only time will tell.
Experts estimate thereโs a strong chance that many developers in the decentralized exchange community will transition toward languages like Rust and Python over the next year. This shift is driven by the practical need for improved transaction processing speeds, especially as crypto volumes surge. While some developers may resist due to the learning curve, enhanced performance could make the change worthwhile. Adoption of new languages might happen at varying rates, but with the right resources, a significant portion of the community may embrace these changes before the end of 2026, as they seek solutions to ongoing challenges in JavaScript.
Consider the electric car revolution that emerged in the early 2000s. Initially, the technology faced skepticism and fears over range limitations. Yet, as pioneers took the leap to innovate, the industry transformed. Similar to JavaScript now, traditional vehicles served their purpose, but the move toward electric technology became essential as demand and environmental awareness grew. Just as early adopters of electric cars led to advancements in battery life and market acceptance, today's developers in the crypto field might pave the way for a new era of programming languages, driving innovation forward just when it seems the limits of existing systems have been reached.
