I'm adding pre-compiled unboujnd scripts, and moving from a pool of 4 isolates VMs in V8 to 1 isolate with a semaphore for concurrency, we'll see if this improveds the CPU and RAM usage

I keep doing tests, a single 4core + 512MB instance, can easily handle 15000 requests with 250 concurrency in barely 9 seconds, with a 1600~ req/s average. 100% success on requestas and backend data relay to GA.

Added proper (zstd) compression to Tagpiper and improved connection handling—now it’s faster than ever.

Trying to run some benchmarks,SGTM vs TagPiper.For now just plain HTTP performance.
One limiting the instances to 512Mb RAM and 1 CPU to match usual Cloud Run setup
Second one unlimited. SGTM is not using multithread so not much comparable,also not usually needed since you'll likely using one CPU.

I'm pretty bad on this... but how can I load a local Docker on a Cloud run ?

The current tagpiper metrics for GA4 hits for example looks pretty good.

I'm trying to build GTM Templates like sandbox that will replicate the current GTM code, this would make easier for people to migrate their templates, or even at some point making GTM ones directly to work on TagPiper

I think I'm moving to use v8 engine instead of GOJA,while the difference for the server-side usage won't make any big difference having full access to JS ES6+ will make some future features possible,but since this needs CGO,container size will upgrade to 95ish mb,which shouldn't either be a big deal
