For now ThinLTO summary file has the same size of IR bitcode file, while it should be much smaller than that, since only the ModuleSummaryIndex, IRSymtab and Strtab should be written in it. GUID-ValueID map and original name are required in ThinLink phase, which are not included in module summary. If we want to reduce the summary file size, we should add these records into module summary, so in the next patch, we can do the reduction based on this change.
