Observing very high throughput in Truclient chrome compared to Truclient Firefox

Hi All,

As part of regression performance testing, we are testing an application with 74 users for steady steady state duration of 30 minutes each month using scripts developed in Truclient Web - Firefox. Recently, we moved our scripts to Truclient Web - Chrome and tested the application with 74 users for the same steady state of 30 minutes.

In the test with Truclient Web - Chrome, we are observing very high total throughput close to ~7.7 GB, whereas when we tested the same in Truclient Web - Firefox, its close to ~250 MB.

(FYI - The response times in both Firefox and Chrome is comparable).

We wish to know if anyone else faced the similar issue with high total throughput or would like to know what might be the cause of it.

Any suggestions would be really helpful.

Re: Observing very high throughput in Truclient chrome compared to Truclient Firefox

Hi there - this seems like an enormously huge delta. I've only just now switched to a TruClient solution, but I see a very surgical selection of extended logging options available in the Runtime Settings. Have you inspected what you're getting back in the Response Body?

Please reply back with your findings as I'm sure we'd all be interested on what's going on here.

Re: Observing very high throughput in Truclient chrome compared to Truclient Firefox

When the amount of work per user is more or less equal (same response times seems to indicate this), a possible candidate to look at is how does both browsers behave in respect to caching.

Also internally we saw some high load due to TruClient Chrome: Two users generated more load than a 100 users via HTTP/Web script. So we think it is related to browser caching behavior. We expect it has to do with going from iteration to iteration.

Search the web for 'TruClient browser cache' and you will find more to investigate.
