Scalability of JVM processes is limited by GC rate.
For contemporary CPUs and GCs that provide the best throughput the allocation limit is ~11Gb/sec.
After reaching the allocation limit the JVM process doesn't scale.
Having 7.5Gb/sec in 1 thread the limit will be reached at 2-4 threads and adding more threads only decrease the total troughput.
Steps to reproduce that by running JSON parsing benchmarks on your JDK:
sbt and/or ensure that it already installed properly:
| git_current_branch () { | |
| local ref | |
| ref=$(command git symbolic-ref --quiet HEAD 2> /dev/null) | |
| local ret=$? | |
| if [[ $ret != 0 ]] | |
| then | |
| [[ $ret == 128 ]] && return | |
| ref=$(command git rev-parse --short HEAD 2> /dev/null) || return | |
| fi | |
| echo ${ref#refs/heads/} |
| // Method to test | |
| public uploadFileList(files: FileList) { | |
| // whatever | |
| } | |
| // Test | |
| it("uploadFileList", () => { | |
| const blob = new Blob([""], { type: "text/html" }); | |
| blob["lastModifiedDate"] = ""; | |
| blob["name"] = "filename"; |
