Oh good!

It happens consistently when I serialize via:
  FLSerializer serialize: anObject toFileNamed: aFileReference fullName.
I can send you the image if necessary. I'll PM you if we can't figure it
out.

Not sure. I evaluated the above line in default Pharo 4.0. Does that answer
it?

[Pharo-users] Fuel Slow?

[Sean P. DeNigris]

I'm serializing about 20MB of data with Fuel and it takes about 45 seconds.
Is that normal? Can anything be done to speed things up?

Thanks!

No, it's not.

Can I reproduce it? If true, tell me exactly how (if you give me the image
and tell me which VM you used, even better).
Which stream are using?
Did you profile it?
