So sorry I missed that. After loading the cpuprofile into the profiler it seems that t.guid is the bottleneck. Looking at out/client/extension.js, I see t.guid in the context of what appears to be inversify library code. We’re on version 4.13.0, which is deprecated, and inversify actually deprecated their use of GUIDs 2 years ago with version 5.0.1. Perhaps we should bump our inversify version? /cc @DonJayamanne @rchiodo @IanMatthewHuff @DavidKutu

Hi @ydennisy, thanks for checking in. Our December release included a dependency upgrade which should reduce the impact of t.guid on performance. If you are still encountering high CPU load, please open a new GitHub issue with the CPU profile the way that @oligu did, as it’s possible the performance issue you are observing is caused by something else.
