Hello, Sorry for the late reply. I do not use lemmy that often and only saw this now when I came here to post about new release. You’re right to call that out. I made an oversimplified claim. Let me clarify, XML vs JSON performance is nuanced:

1. Parsing speed: JSON is generally faster to parse than XML because:

• Simpler syntax (no opening/closing tags, no attributes vs elements decisions)
• Less data structure overhead
• More direct mapping to native data structures in most languages

2. Payload size: XML is typically more verbose due to:

• Opening and closing tags
• Namespace declarations
• Attribute syntax
• This means larger network transfers

However:

• Well-optimized XML parsers can be very fast
• The difference matters more for high-volume APIs than occasional journal syncs
• For large text content (like journal entries), the actual content dwarfs the format overhead
