[Bug 63639] New: give you three times qps improve
https://bz.apache.org/bugzilla/show_bug.cgi?id=63639
Bug ID: 63639
Summary: give you three times qps improve
Product: JMeter
Version: 5.0
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: HTTP
Assignee: issues@jmeter.apache.org
Reporter: 206763753@qq.com
Target Milestone: JMETER_5.2
i write my jxm as the attachment image sax.png, with 31 or 100 threads ,i got
6300 qps
all.txt size is 113M, with 10800000 lines in.
then, i wtite 31 threads(Runable),igot 14000qps, many times.
so,i doubt that your file loader must have threads compete, and i suggest that
you can split the big test data file to thread number parts; so there is no
competition; i am sure this will improve the qps i can got

Which version of JMeter are you using? You said 5.0 in the meta data but 3.2.x
in your comment, or have I misunderstood?

Finer locks for FileServer
This is mainly a test, whether finer grained locks for FileEntries in
FileServer would speed up multi-threaded usage of files in CSV data source.
It didn't speed up things on my setup.

i thought that "CSV Data Set Config" element read file content to a list; but
all user thread get data from this list,so there must be competition.
i thought this can explain why my handcode threads load test get 14000qps, but
jmeter get only 6300qps.
my handcode threads initialized with thread's own data, no competition;
my solution was given at bug description

In my tests, I got over 400.000 qps using a CSV data source and a debug
sampler. It didn't matter whether I used 8 threads, 100 threads or 1000
threads.
Could you be more specific and share a test, that you use (it should be
minimalistic)?
I even looked into the FileServer implementation (that class gets used, when
you configure a CSV data source) and changed the locking to be a bit finer
grained. It didn't change the number of qps. It made the max duration a bit
lower. I will attach the patch, so you can check, if it helps in your setup.

There is not enough information here for me to understand, what your problem is
or how you suggest, we should solve it.
I suspect that you should discuss your problems on JMeter users mailing list
first.
