Technical Guide & Sysadmin Recommendations
Authored by HostRating.org Engineering TeamTuning Enterprise Runtimes for High Throughput
Java Spring Boot applications and ASP.NET Core web services require dedicated memory space to prevent aggressive garbage collection pauses. In multitenant shared environments, unexpected CPU throttling during a GC cycle can freeze your application for several seconds.
On IwiHost's DDR5 ECC RAM or GhostRDP's dedicated Windows nodes, JVM Garbage Collectors (ZGC or G1GC) and .NET Kestrel pipelines run with near-zero latency overhead.
