No real issue found in snapshot in comment (1), except very long processing of Document.insertString() called from loadSwingDocument. Also insertString() is called multiple times from 1 loadSwingDocument - the implementation inserts individual lines into document: not necessary, can use some fixed-size buffer for loading.
Snapshot in comment #2 shows completion waiting on HTTP while downloading external entity definitions. Will not fix, it's a network issue.
Reports processed up to 2012-10-22 (#62868). Summary for the processed reports: 587699, 598517, 608418, 620028, 620189: seems like evaluation of a rather complex schema with respect to substitutions, no fetching done. However loading all schema models takes 0,6sec and their processing another 0,5sec. 620013, 620014, 620015: retrieval from URL 585525, 586065, 602594, 611547, 613221, 618745: lot of time is spent in schema document load, through loadSwingDocument which loads line after line. Lot of processing is triggered after each insertString. 618517: WSDL parsing of downloaded stuff takes 43% of schema downloader time. 609604: initialization of Spring XML completion 587699, 602566: addNSAwareCompletionItem triggers model creation, since the replacement text is being constructed. Not relevant (covered above, or non-errors): 584855, 584856, 585327, 585465, 586126, 586162, 586469, 586478, 587577, 588515, 589077, 590456, 590963, 590975, 591592, 592670, 592720, 592755, 592821, 593040, 593482, 594211, 594337, 595351, 595405, 595406, 595407, 595408, 595409, 595410, 595411, 595776, 597238, 597771, 597940, 598293, 598294, 598295, 601088, 609605, 616618, 617335, 617499, 617685, 618517, 619299, 620868: retrieval of remote resource. 619923: treshold of 750ms spent in classloading and partially in FXML completion - in Java model. 618935: initialization of various providers (classloading) + loadSwingDocument. 612598: classloading, cancelling maven process (but waiting properly for cancel to finish, no defect) 587287, 591555, 599648, 600798, 600826, 606519, 607441: initializing IDE. Lookup initialization is on the stack. Class+resource loading
