A lot may also depend on the size of the HDD. I did not notice an issue syncing with a 2 TB HDD on Trisquel 7. I do suspect this can be an issue with a smaller HDD.

One other thing is that virtualization itself can be very hard on an HDD when both the host OS and the guest OS are on the same drive. If one adds to this a disk intensive application in the VM then I can see this problem developing. My experience with this has been with Windows VMs running on GNU/Linux hosts where I found a significant performance improvement by having the Windows VMs on a different HDD from the ./ GNU/Linux partition. The latter partition had the OS files. When I moved my laptop which had a single drive setup from an HDD to an SSD, I saw see a significant improvement in the Windows VM performance.

Hi there.

I've built and been running the following on a ubuntu 15.10 VM (12 Mb RAM) - Win7 Native - with encypted drive, Intel i7-4790k @ 4Ghz - 32GB Ram :

ahh - no svn info equivalent with git - ok - last commit info

Code:

commit 3a4db6346b2b1b4c3e3733d833f338d104f7da95
Merge: 0eb3b66 7f77b23

    Merge pull request #533
    
    7f77b23 posix_daemonizer: only create the main daemon object in the last child (moneromooo-monero)

Some feedback - the RAM usage is much better, but the syncing process is hammering my harddrive, to the point where not only the VM becomes unresponsive (10-20 second pauses but VM is still stable), but also any disk access on my native machine significantly slows down applications running there.

Changing limit_up and limit_down values has little effect.

I'm going to have a little peek at the database code tonight to get familiar to see how its working.

Just wanted to give a heads up as I suspect when the next database version is released you may find the complaints switching from RAM usage to HDD usage.

Good points. But when you think about it, given that the database is going to be around 10 GB and it is possible under ideal conditions to sync in a about an hour, that is going to be a lot of disk writing over the course of that hour. There is probably value in a "background sync" mode that deliberately takes longer with a less intense workload. A better implementation of down_limit would probably do the trick. Obviously that can come later after 0.9.

Also, I have to say that an SSD is pretty recommended here. HDD does work, but obviously for any database-type workload with a lot of random access, SSD is just going to work much better.

Thanks for the test report and any further effort put into testing.

I have working on create Monero tutorials for my website (8xmr.com) based on information have found on getmonero.org, Reddit and elsewhere.

I decided to start working on an openalias tutorial and felt embarrass that I never took time to create alias myself.

So easy! Took me 5 minutes to create my monero alias. Now I have some more marketing ideas for openalias and monero

I am looking forward to hearing more about how you plan to market Monero and OpenAlias!

Should monero.win.x64.v0-9-beta be started with old .bat file or is there any new way to start bitmonerod and simplewallet?

it should be the same... the bat file should just be calling bitmonerod.exe with whatever flags you need. if in doubt, just open the .bat file in notepad to get a sense of whats going on.

Looks like warptangent fixed the DNS issue (PR #541) so there should be no issue of leakage or some functions not working now.

Monero 0.9 beta still consumes a lot of memory when I synchronize blockchain that wasn't updated for 15 days.

In Windows 7:

+ Working memory: 2114890Kb (~2GB)
+ Elapsed time: 2.5 hours (very slow I think)

Is that the first 0.9 Beta or the second?

The second which is built on Nov 01, 2015

The good news is that once your blockchain is in sync then memory usage will decrease dramatically

LMDB only takes what it can take (during syncing). If much of your RAM is already allocated, LMDB won't take it while syncing. In other words, it won't get stuck like for instance the old binaries. After syncing it only takes <100 MB.

There's a second beta? I'm upgrading then. The first was already a great improvement (I couldnt run before with 4GB of RAM).

Yeah:

Be cautious, direct link in that thread! Also, always thread beta with the appropriate amount of caution.
