Extremely Slow Performance on MacOSX

[Yada]

Hello. I've just successfully delivered an xQuery-based project for the defense department. Although I was extremely impressed with oXygen's functionality, its performance was a major hinderance, at times bordering on unusability.

Environment was G5 Imac with 2gB RAM, latest oXygen, with jvm ram allocation incrementally increased to 1.5gB in unsuccessful attempts to improve performance by editing the oxygen plist. The XML input files were excel spreadsheets exported to XML Spreadsheet, the largest being 2.4mb. The xquery was about 4.8K with straightforward xPath, simply converting the inputs to CADM XML.

Symptoms were *long* delays (many minutes; >5) starting a debug run, resuming a run from breakpoints; in fact; on almost every operation. Activity monitor sampling showed many threads active but seemingly blocking in the kernel somewhere. No clear pattern there.

The project is over now, but I'd sure like to know what's going on in case we ever try to use oXygen in the future. Right now, that seems unlikely; this was just too painful to contemplate.

Hello,

It will really help if you can provide a sample and a description of the steps to take to obtain that behaviour. If you can do that please send them (ar a link to the files) to support at oxygenxml dot com.

Thank you,
George

Hello Brad,

Thank you for sending the files. All you have to do is to disable the "Enable XHTML output" option that you do not use anyway. As you can read on that page of the User Manual:

For performance issues, it is advisable to disable XHTML output for large jobs.

If you do a search for the word "slow" in the Search tab of the Help dialog opened from menu Help -> Help the first match is question and answer 3 from the Common problems section of the User Manual which describes what you should do in your situation.


Regards,
Sorin
