Description

GC performance is affected when the key is a complex data structure. We can make it

private static WeakIdentityMap<String, EtagCacheVal> etagCoreCache = WeakIdentityMap.newConcurrentHashMap();

instead of

 

private static WeakIdentityMap<SolrCore, EtagCacheVal> etagCoreCache = WeakIdentityMap.newConcurrentHashMap();
