[Glass] GsFile >> #next at least 4 times slower than Pharo

Hi guys,

I am processing some large files and I find out that GsFile reading is way slower than it is in Pharo. At least 4 times slower. The way I am opening the file is:

 GsFile openReadOnServer: aFilename

and then... for my benchs I simply iterate and do a #next.

Is there some setting maybe I can set to GsFile instance that would give me a speedup? or it's simply the way the file primitives work in GemStone?

Thanks in advance,

OK, good. Just wanted to be sure I wasn't missing something obvious. And
yeah, I saw that...checking in #next and friends I saw you had to do quite
some logic every time to check wether you were in client or server side...
  3.3 looks promising.

I think that folks have tended to load the contents of the file into a

Yes, I did that for SIXX export / import. But in this case I am dealing
with a 1GB text file..... 27MM or rows :)

But thanks for the tip, though.
