Thank you for the idea!
Now it has the default value (8 hours). But I see that the remaining time for the last task is about 24 hours (with deadline 26th of Apr). And according to my previous observations the real completion time can be multiplied by 1.5 :)

Jord, Rosetta@Home project.
Well it's actually 1.5Ghz (base) CPU.
Yes, theoretically it can rise up frequency up to 2.3GHz, but it's only possible in 1-core workload. Meanwhile, BOINC run 2, and there is a few extra processes. So, I never saw 2.3MHz.

Bryn Mawr: thank you so much! Indeed, there was 'Store up to an additional 0.5 days of work' parameter. I decreased it to 0.1 and hope this helps.

Jord: Yes, the CPU is really no so fast, because it's low-power Intel Celeron J3455. The core of NAS device with no fan configuration. It mostly idle, so I decided to add some work to it.

I noticed that BOINC client takes new task even current running task are not completed yet.
For example, I have 4-core CPU and Computing Preferences: Use at most 50% of the CPUs.
So, it is supposed to have the only 2 active tasks the device can compute simultaneously.
At the start, the client takes 2 tasks to compute. It's ok.
But at the next day it takes 1 extra task, while previous are not completed yet.
As a result I have 2 computing tasks (and will be computing at least couple of days) and 1 in Ready to start status.
But it have no sense! The pending task will never be computed in a scheduled time. In fact, it probably will be started after the deadline comes.

How can I disable taking tasks in advance by BOINC client/BOINC manager?
