The Windows EWS bots process patches fairly quickly. Once I corrected the problem today, it managed to process about 97 patches in about an hour.
I do think one bottleneck is due to individual EWS bots “locking” patches. The first bot to reach a patch locks the patch against other bots handling it. If the patch happens to be ‘consumed’ be a bot with some kind of problem (e.g., bad local configuration, a full disk drive, etc.), that patch will not be touched again — even if the other eight EWS bots are sitting dormant. Is there some other processing metric you are concerned about?
