Because it doesn't take the same code path (GML uses /vsicurl_steaming/ while other output formats use CPLHttpFetch() that downloads the whole file into memory and then parses it). I've just added GZip compression request in /vsicurl_streaming/ (can be turned off by setting CPL_CURL_GZIP to NO) > > Thanks, > Jeremy > > This message contains information, which is confidential and may be subject > to legal privilege.
