Recurring performance problem

I have a recurring performance problem with memoQ.

I have the situation that memoQ periodically requires approx. 20 seconds before it responds (this occurs every few minutes).
The only solution I can find is to restart memoQ until it runs normally (sometimes several times), after which it continues to run normally (until restarted, after which the problem may recur). If memoQ has this performance problem, it continues to run poorly (until restarted, after which the problem may recur).
Does anyone else have the same problem, or more importantly, do you have a better solution?

A long shot, but... May 29

This loss of performance sounds like a memory leak. I doubt it will be in memoQ, but it would not surprise me if it was a leak in Microsoft Word, because perhaps you are using Word for spellchecking on the fly. You can disable spelling on the fly and simply spellcheck at the end, or else use Hunspell as your spellchecker. Check the online help as to how to do it (I would love to help, but am extremely pressed for time today).

(Yes, I know that Hunspell does not check for grammar. What I do is, at the very end of each job, do an export to a bilingual RTF file and run spellchecker in Word in one go.)

Task manager May 29

You could try keeping Task manager open and check CPU/memory allocation when the "freeze" happens to see whether there's some task/program in particular that is draining too many resources.

That's how I found out that Microsoft Edge seems to cause a memory leak on my machine (with W10) if left open for a while (as it ended up gobbling something like 2.5 GB of RAM with just 3 tabs open...).

Personally, I think I never experienced what you describe with MQ, but perhaps it's also linked to what resources you're using? Like, for instance, enormous TMs, server projects, synchronization options, etc.?

Memory May 29

You don't say which version you're using.

MemoQ 2015 sometimes goes in a memory-eating frenzy where it begins to eat up all available RAM up to my 8 GB, making the computer grind to a halt. I have taken it in using 2 GB for a text of relatively modest size. It seems to happen in technical texts with many special characters.

I reported it to Kilgray support long ago, but getting them to fix things can require a lot of patience.

Performance problem May 30

After running memoQ for several days without problems (I put my computer into "Sleep" mode overnight), I was forced to restart memoQ (because it went into a loop after I pressed an unwanted key combination), and surprise, ..., the performance problem has recurred.
This seems to indicate the problem lies with memoQ (2015).
I opened Windows Task Manager - it did not show any obvious performance problems:
Memory approx. 2.4 GB (4 GB available), main user memoQ (265 MB)
CPU: approx. 20%

Update: After successively "killing" non-essential processes, the "brake" seems to be released. The problem seems to be caused by some unknown (to me) trace process.

Performance problem Oct 3

This problem keeps reoccuring, but I have found that memoQ "corrects" itself after several minutes (sometimes as long as 20 minutes)
