I have deployed war file of my jruby application on glassfish server. i have noticed that my application becomes slow as time passes. My server is of 30GB RAM but still application is very slow.
Every ruby method in my application is creating array which contains around 1 millions of records. i think creating such big array is causing memory issue and hence application is becoming slow. if this is true then what setting can be done to avoid such memory issue.
Below is my memory setting for java
uintx AdaptivePermSizeWeight = 20 {product}
intx CompilerThreadStackSize = 0 {pd product}
uintx ErgoHeapSizeLimit = 0 {product}
uintx HeapSizePerGCThread = 87241520 {product}
uintx InitialHeapSize := 1055640320 {product}
uintx LargePageHeapSizeThreshold = 134217728 {product}
uintx MaxHeapSize := 16890462208 {product}
uintx MaxPermSize = 174063616 {pd product}
uintx PermSize = 21757952 {pd product}
intx ThreadStackSize = 1024 {pd product}
intx VMThreadStackSize = 1024 {pd product}
java version "1.7.0_101"
OpenJDK Runtime Environment (IcedTea 2.6.6) (7u101-2.6.6-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
Thanks
