We think that this bug might be related to #vip-vsb

I'm not seeing the same performance issue on Android native. As the issue is also a generic performance issue I'm demoting it from a blocker.

[roryabraham]

I think this is too generic to be useful as an issue, but I'll bring it up in #newdot-performance

[Julesssss]

Further investigation into homepage initial render shows this is an outlier:

[Julesssss]

Continuing discussion in Slack, as there is data showing an increase in render time for app switching.

Investigated to be the bottleneck on getSearchText() processing for a lot of personalDetails on an account (string concat).

Linked by @danieldoglas to #38887 - reverted in #40019. The initial bug needs a new solution to the problem.

[Julesssss]

Great find. Lets just make sure to check our internal timings revert to normal before closing this issue out

[roryabraham]

ok, looks like this has probably been fixed but we'll double-check before shipping the checklist

Contributor+: @jayeshmangwani paid $250 via Upwork.

d'oh, sorry about that, you'd think that I would know, having invited you to NewDot payments. More of a knee-jerk habit. I paid via Upwork cuz I already clicked the button before I saw your comment abovve, sorry.
