I met perf issues under heavy load and would like to resolve them. I'm using 4.1 version. Here is profiler output: 26% org.apache.http.impl.client.CloseableHttpClient.execute(multiple parameter matches) :26,107,40 26% org.apache.http.impl.client.CloseableHttpClient.execute(org.apache.http.client.methods
