[Fix #10460]: Pre-size ProxyContext map to avoid HashMap resize on request path

[HarshMehta112]

Which Issue(s) This PR Fixes

• Fixes [Enhancement] Set initial capacity for ProxyContext internal HashMap to avoid resize #10460

Brief Description

ProxyContext is created on every gRPC/Remoting request. Its value map used the default HashMap capacity (16, threshold 12), so adding the 10 ContextVariable keys plus interceptor entries triggers a
resize on the hot path. Pre-size the map to avoid it:

private static final int DEFAULT_INITIAL_CAPACITY = 64;
private final Map<String, Object> value = new HashMap<>(DEFAULT_INITIAL_CAPACITY);

No behavior or API change.

How Did You Test This Change?

Pure capacity refactor, no logic change. Existing proxy module tests pass.

Review: Approved ✅

PR: #10461 — [Fix #10460]: Pre-size ProxyContext map to avoid HashMap resize on request path
Type: Performance optimization (1 file, +2/-1)

Assessment

Valid performance fix. ProxyContext is created per gRPC/Remoting request, and its value map previously used the default HashMap capacity (16, threshold 12). Adding ~10 ContextVariable keys plus interceptor entries would trigger a resize on the hot path.

Changes

• Pre-sized HashMap to 64 (threshold 48), well above the expected key count
• Minimal, focused change with no API impact

Verdict

✅ Clean, well-targeted optimization. Fixes #10460.
