World: r3wp

-- Do you have a _lot_ of private messages between you and Chris?

-- Do you see similar delays when private messaging with other members 
of this world?

[It could be that the private message distribution process is affected, 
while the broadcast of public messages is  not]

i think it's time dependent

Thanks. That suggests the server running this world gets overloaded 
at times.

let me see how long this takes to post

3 secs

but 7 seconds to send a private message

a simple load indication from the server could tell something

private messages are single HUGE bin for every user.

so if you've PM many times in the past with anyone, it all adds up. 
 this *is* a design issue.

some groups also have started to become rather slow (the view group, 
for example)

Hmm, so if Graham rejoined as GChiu (say) he'd have an empty private 
message set, and his messaging would be fast again....

....Sounds like a good justification for a second account for a prolific 
member of a busy world.

....Or for AltME to provide a purging mechanism for old private messages.

(If the private message slowdown is true, that is.)

it is... I've discussed it directly with Carl  :-)

Did you test it as well?

discussion != empirics

yes.  I often create private groups to chat with people so its not 
mind-bogling slow.

Well, I guess someone should then revamp the storage mechanism.

Altme should really be released open source so we can fix these things.

My whole REBOL3 world data is a mere 62M on disk. Any noticeable 
slowdown occurring for this puny amount of data is somewhat .... 
surprising, to stay polite.

it has to transfer & update large blocks, which is where I guess 
the slowdown is...

Well, it surely does not post back the whole chatset just for adding 
a single message ...

But maybe it does :) Who knows but Carl and those who wrote it :)

that would be carl too  ;-)

It'd be interesting to know the size of Graham's private messages 
file  -- 19.set in his case.  {Andreas, yours would be 107.set]

The files should be in altme/worlds/rebol3/chat

But beware that Windows may be virtualising the files, so the latest 
copy may be well hidden elsewhere,

It seems there's noone who wrote altme ... it just came from the 
outer space :-)

My private messages file is 384K.

Mine is 1.6meg. I suspect Graham can top that!

3 523 969 bytes :-)

I am a politician - I do many behind-the-scenes activity :-)

4.5MB here.

That's large, Maxim.

For comparison, the largest public,active, group is Core -- I see 
that as 3.8 meg in size.

yes... and its why I PM so little now.  its just painfull.

this group is < 1 sec.   PM sometimes even causes my altme to go 
into "internet busy" mode for so long, I loose track of the discussion.

I can see one larger group....REBOL3-old was 4.3meg.

And that was retired and replaced by the REBOL3 precisely because 
of the speed problem.

Doesn't the speed also have to do with the message limit per chat 
settings? I've decreased mine and  it's much faster. Though I do 
wonder how accurate that setting is or what it really measures. I 
set mine to a higher number after a search and warning that it needs 
to be set higher. I've thought that there's no way there could be 
that many messages (several 1000's) in that one topic.

it just limits what is visible in your scrollable view above.   it 
will affect speed so much as it uses less faces to display the list 
and thus less RAM is managed by the GC.

Yeah, I guess I should just search the data directly when I'm looking 
for something really old.

doing an OS (file content) search in the altme directory usually 
is easier and faster too.

Plus the [web-public] groups have a fast search on REBOL.org
    http://www.rebol.org/aga-search.r

19.set is a puny 4.2mb

:) It's one of the larger ones, I'd guess, even if Maxim is just 
ahead.

If you send a private message to yourself -- is that fast or slow?

he was hoping it would be twice as large as mine... but mine is bigger 
 ;-)

16 seconds to message myself

Awesome :)

So, it does appear to be group dependent

reminder to myself .. don't message myself !

Any chance to check if there's heavy network traffic during those 
16 seconds :) ?

I could look at the back off my laptop and count the flashes??

ok, I've got the windows task manager networking tab up now.

that message was not even a blip
