Research direction

No repository file or test is named. Reproduce the issue using the Python imports and GraphServiceClient sequence shown, then compare the first and second await client.me.get() calls. Done means identifying and addressing the cause of the extra first-request latency and verifying the behavior with a regression check.

Description

status:needs-discussion

Not sure if performance is a feature request or bug.

import win32gui
from azure.identity.broker import InteractiveBrowserBrokerCredential
from msgraph.graph_service_client import GraphServiceClient

1.1s (Already in issue #904)

current_window_handle = win32gui.GetForegroundWindow()
credentials = InteractiveBrowserBrokerCredential(
    tenant_id=tenant,
    client_id=client_id,
    use_default_broker_account=True,
    parent_window_handle=current_window_handle,
)

0.0s (Expected)

client = GraphServiceClient(
    credentials=credentials,
    scopes=[]
)

0.4s (Slower than I would expect)

await client.me.get()

2.2s (1st request. This is significantly slower than I would expect)

await client.me.get()

0.1s (2nd request. Expected)
