            Right now we've tested only with primitive values passed into the Gatling session. It may work if you convert the data into a java.util.Map. So maybe your best bet is to write some toMap() function on your data-object. Or if you manage to emit a JSON string, there is a karate.fromString() helper that can be useful.

            So please read the docs here and figure out what works: https://github.com/karatelabs/karate/tree/master/karate-gatling#gatling-session

            Faulty benchmark, puzzling assembly
            Asked 2022-Mar-28 at 07:40

            Assembly novice here. I've written a benchmark to measure the floating-point performance of a machine in computing a transposed matrix-tensor product.

            Given my machine with 32GiB RAM (bandwidth ~37GiB/s) and Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (Turbo 4.0GHz) processor, I estimate the maximum performance (with pipelining and data in registers) to be 6 cores x 4.0GHz = 24GFLOP/s. However, when I run my benchmark, I am measuring 127GFLOP/s, which is obviously a wrong measurement.

            Note: in order to measure the FP performance, I am measuring the op-count: n*n*n*n*6 (n^3 for matrix-matrix multiplication, performed on n slices of complex data-points i.e. assuming 6 FLOPs for 1 complex-complex multiplication) and dividing it by the average time taken for each run.

            Code snippet in main function:

            Answered 2022-Mar-25 at 19:33

            1 FP operation per core clock cycle would be pathetic for a modern superscalar CPU. Your Skylake-derived CPU can actually do 2x 4-wide SIMD double-precision FMA operations per core per clock, and each FMA counts as two FLOPs, so theoretical max = 16 double-precision FLOPs per core clock, so 24 * 16 = 384 GFLOP/S. (Using vectors of 4 doubles, i.e. 256-bit wide AVX). See FLOPS per cycle for sandy-bridge and haswell SSE2/AVX/AVX2

            There is a a function call inside the timed region, callq 403c0b <_Z12do_timed_runRKmRd+0x1eb> (as well as the __kmpc_end_serialized_parallel stuff).

            There's no symbol associated with that call target, so I guess you didn't compile with debug info enabled. (That's separate from optimization level, e.g. gcc -g -O3 -march=native -fopenmp should run the same asm, just have more debug metadata.) Even a function invented by OpenMP should have a symbol name associated at some point.

            As far as benchmark validity, a good litmus test is whether it scales reasonably with problem size. Unless you exceed L3 cache size or not with a smaller or larger problem, the time should change in some reasonable way. If not, then you'd worry about it optimizing away, or clock speed warm-up effects (Idiomatic way of performance evaluation? for that and more, like page-faults.)

            1. Why are there non-conditional jumps in code (at 403ad3, 403b53, 403d78 and 403d8f)?

            Once you're already in an if block, you unconditionally know the else block should not run, so you jmp over it instead of jcc (even if FLAGS were still set so you didn't have to test the condition again). Or you put one or the other block out-of-line (like at the end of the function, or before the entry point) and jcc to it, then it jmps back to after the other side. That allows the fast path to be contiguous with no taken branches.

            1. Why are there 3 retq instances in the same function with only one return path (at 403c0a, 403ca4 and 403d26)?

            Duplicate ret comes from "tail duplication" optimization, where multiple paths of execution that all return can just get their own ret instead of jumping to a ret. (And copies of any cleanup necessary, like restoring regs and stack pointer.)

            QUESTION

            What difference does it make if I add think time to my virtual users as opposed to letting them execute requests in a loop as fast as they can?
            Asked 2022-Mar-16 at 20:38

            I have a requirement to test that a Public Website can serve a defined peak number of 400 page loads per second.

            From what I read online, when testing web pages performance, virtual users (threads) should be configured to pause and "think" on each page they visit, in order to simulate the behavior of a real live user before sending a new page load request.

            I must use some remote load generator machines to generate this necessary load, and I have a limit on how many virtual users I can use per each load generator. This means that if I make each virtual user pause and "think" for x seconds on each page, that user will not generate a lot of load compared to how much it would if it was executing as fast as it could with no configured think time - and this would cause me to need more users and implicitly need more load generator machines to achieve my desired "page loads per second" and this would be more costly in the end.

            If my only request is to prove that a server can serve 400 page loads per second, I would like to know what difference does it really make if I add think times (and therefore use more virtual users) or not.

            Why is generally "think time" considered as something which should be added when testing web pages performance ?

            1. Virtual user which is "idle" (doing nothing) has minimal resources footprint (mainly thread stack size) so I don't think you will need to have more machines

            2. Well-behaved load test must represent real life usage of the application with 100% accuracy, if you're testing a website each JMeter thread (virtual user) must mimic a real user using a real browser with all related features like

              the most straightforward example of the difference between 400 users without think times and 4000 users with think times will be that 4000 users will open 4000 connections and keep them open and 400 users will open only 400 connections.

            K6 currently has only blocking calls so each post will finish fully before the next one starts.

            On the loop question you have two(three) problems:

            • createdISCompleted is unitialized, so the while loop will never be run as it's not false.
            • you have big S in the declaration but then you have small s in the while loop.
            • you have break at the end of the loop which means it will always exit after the first iteration.

            Just add JSON JMESPath Extractor as a child of the request which returns the above response and configure it like:

            • Names of created variables: anything meaningful, i.e. clientTransactionId
            • JMESPath Expressions: clientTransactionId
            • Match No: 1

            Once done you will be able to refer extracted value as ${clientTransactionId} JMeter Variable where required

            applicationTransactionId can be handled in exactly the same manner

            Asked 2022-Jan-13 at 05:05

            I was looking for the verbal explanations of different performance testing types and saw a new one called "breakpoint test". Its explanation seemed very similar to stress testing for me. So what is the difference, or is there any difference?

            Stress Test: A verification on the system performance during extremely high load which is way above the peak load

            Breakpoint Test: This test determines the point of system failure by gradually increasing the number of simulated concurrent users.

            As far as I know, we increase the load gradually while performing stress test too. So what is the difference between this two type?

            From the workload point of view the approach is exactly the same, my understanding is:

            • Stress test is about finding the first bottleneck, it's normally applied before deployment or even at early stages of development (see shift-left concept)
            • Breakpoint (sometimes also called Capacity) test is about checking how much load the overall integrated environment can handle without issues and what is the slowest component which is a subject for scaling up/optimization.

            LONGTEXT columns are stored separately from the rest of the columns. Extra disk fetches are used to load the value.

            When you separated the LONGTEXT columns out, did you then fetch the value? And that was slow, anyway?

            Do you have INDEX(shop_id)?

            Did Laravel do something dumb like preload the entire table?
